Alaska inheritance laws distribute a deceased person’s property through one of three channels: a valid will, intestate succession when there’s no will, or beneficiary designations on accounts and policies that bypass probate entirely. Alaska imposes no state estate tax and no inheritance tax, so heirs receive their shares without any state-level tax.1Alaska Court System. Federal Tax Matters Federal estate tax only reaches estates above $15 million in 2026, which puts the vast majority of Alaska families outside its scope.2Internal Revenue Service. Estate Tax What actually determines who gets what is the set of rules below.
When There Is a Will
A valid Alaska will must be made by someone at least 18 years old and of sound mind, put in writing, signed by the maker (or by another person at their direction), and signed by at least two witnesses.3Justia. Alaska Code 13.12.504 – Self-Proved Will If the will meets those requirements, it controls distribution of the probate estate.
Alaska also recognizes holographic wills, which are handwritten and don’t require witnesses. The signature and the material portions — the parts that identify beneficiaries and gifts — must be in the maker’s own handwriting.4Justia. Alaska Code 13.12.502 – Execution; Witnessed Wills A typed document with only a handwritten signature does not qualify. Holographic wills tend to invite disputes over authenticity more often than witnessed ones.
A self-proving will adds a notarized affidavit signed by the maker and both witnesses, confirming the document is authentic. Courts accept the affidavit as proof of proper execution during probate, so no one has to track down the witnesses later.3Justia. Alaska Code 13.12.504 – Self-Proved Will
Alaska does not currently allow electronic wills. The state’s Uniform Electronic Transactions Act specifically exempts wills, and no separate e-wills statute has been enacted.5Alaska State Legislature. Electronic Wills Research A will must be on paper to be valid.
When There Is No Will
If someone dies without a valid will, Alaska’s intestate succession statutes decide who inherits. The estate passes to the closest surviving relatives in a fixed order.
With no surviving spouse, the estate goes entirely to the deceased person’s descendants — children, grandchildren, and so on down the line.6Alaska Court System. Death Without a Will – Intestacy Living children split the estate equally. If a child died before the parent but left children of their own, those grandchildren inherit their deceased parent’s share through what Alaska calls “representation,” which divides the estate at each generational level so family branches are treated equally.
With no descendants, the estate passes to the deceased person’s parents. If no parent survives, it goes to siblings, and from there to more distant relatives: nieces, nephews, grandparents, aunts, uncles, and cousins. Alaska traces the family tree outward as far as necessary. Only if no relatives can be found does the estate escheat to the State of Alaska, which is rare.
What a Surviving Spouse Inherits Without a Will
How much a surviving spouse receives under intestacy depends on who else survives, and Alaska splits this into five scenarios:7Justia. Alaska Code 13.12.102 – Share of Spouse
- No descendants and no parents of the deceased survive: the spouse inherits the entire estate.
- All of the deceased’s children are also children of the surviving spouse, and the surviving spouse has no other children: the spouse inherits the entire estate.
- No descendants survive but at least one parent of the deceased does: the spouse receives the first $200,000 plus three-fourths of the remaining balance, with the rest going to the parent or parents.
- All children are shared, but the surviving spouse has children from another relationship: the spouse receives the first $150,000 plus one-half of the remaining balance.
- The deceased had one or more children who are not the surviving spouse’s children: the spouse receives the first $100,000 plus one-half of the remaining balance.
The last scenario is the one that most often surprises families. When the deceased had children from a prior relationship, the surviving spouse’s guaranteed share drops significantly. On a $500,000 estate, a spouse who would have inherited everything under the “all shared children” rule receives $300,000 under the “prior children” rule.
When a Will Leaves the Spouse Out
Even when a will leaves the surviving spouse nothing, Alaska law provides a backstop. A surviving spouse can claim an elective share equal to one-third of the “augmented estate.”8Justia. Alaska Code 13.12.202 – Elective Share The augmented estate is broader than the probate estate and sweeps in certain lifetime transfers, joint accounts, and other non-probate assets, so a spouse cannot be disinherited by moving everything into beneficiary-designated accounts beforehand.
The elective share must be actively claimed; it does not happen automatically. A surviving spouse who was omitted from a will, or who received an unusually small share, should talk to an attorney, because the augmented estate calculation can get complex.
Children’s Inheritance Rights
Alaska lets parents distribute assets however they choose through a will, including leaving a child nothing. No law requires a minimum inheritance for children. A parent who intends to disinherit a child should make that intent clear in the will to head off later disputes.
The main exception involves children born or adopted after the will was signed. If the parent didn’t update the will and the omission appears unintentional, the omitted child can claim the share they would have received under intestate succession. The protection doesn’t apply if the will shows the omission was deliberate, if the parent left substantially everything to the child’s other parent, or if the parent provided for the child through other means such as a trust or life insurance.
Adopted Children
Adopted children have identical inheritance rights to biological children in Alaska. Once an adoption is finalized, the child is treated as the adopting parent’s child for all inheritance purposes.9Justia. Alaska Code 13.12.114 – Parent and Child Relationship Adoption generally cuts off inheritance from biological parents, with one exception: when a stepparent adopts a child, the child keeps the right to inherit from and through the other biological parent.
Stepchildren
Stepchildren have no automatic inheritance rights. However close the relationship, a stepchild cannot inherit from a stepparent through intestate succession unless legally adopted. To include a stepchild, the stepparent must name them in a will or set up a trust.
Family Protections That Come Off the Top
Alaska carves out protections for a surviving spouse and minor children that take priority over both creditors and the terms of a will. These include an exempt property allowance, which gives the surviving spouse (or the children if there is no surviving spouse) up to $10,000 worth of household furniture, vehicles, appliances, and personal effects over and above any amounts still owed on those items.10Justia. Alaska Code 13.12.403 – Exempt Property A homestead allowance and a family allowance for support during estate administration also apply. These exist to keep the family from being left with nothing while the estate is being settled.
Assets That Skip the Will Entirely
A large share of most estates never goes through probate. These assets transfer directly to the person named on the account or policy, regardless of what the will says:
- Life insurance proceeds, paid to the named beneficiary on the policy.
- Retirement accounts such as 401(k)s and IRAs, which pass to the designated beneficiary.
- Payable-on-death bank accounts, which transfer to the named person at death.
- Transfer-on-death securities, including stocks and brokerage accounts with a TOD designation.
- Property held in joint tenancy with right of survivorship, which passes automatically to the surviving owner.
Because these designations override the will, outdated ones cause real problems. A life insurance policy still naming an ex-spouse will pay the ex-spouse. Beneficiary designations should be reviewed after any major life event: marriage, divorce, or the birth of a child.
Spousal Rights to Retirement Accounts
Federal law layers extra protection onto employer-sponsored retirement plans like 401(k)s and pensions. Under ERISA, a surviving spouse is automatically the beneficiary of these plans. Naming anyone else requires a written waiver from the spouse, witnessed by a notary or plan representative.11U.S. Department of Labor. FAQs About Retirement Plans and ERISA This federal protection applies regardless of what Alaska law or the will provides. Traditional IRAs are not ERISA plans and follow the account’s beneficiary designation without any spousal consent requirement.
How the Estate Gets to the Heirs
Probate is the court-supervised process for validating a will, paying debts, and distributing assets. Alaska offers three paths depending on the estate’s size and whether anything is contested.12Alaska Court System. Probate – Getting Started
For small estates, heirs can skip court using a collection affidavit when all Alaska-registered vehicles are worth $100,000 or less and all other personal property is worth $50,000 or less, both measured after debts and liens are subtracted.13Alaska Court System. Probate – Collecting Personal Property Without a Court Case This procedure doesn’t cover real estate.
Informal probate is the streamlined path when nobody disputes the will’s validity or who should serve as personal representative. Most informal cases don’t require any hearings.14Alaska Court System. Informal Probate Formal probate, with hearings and direct judicial oversight, is used when disputes arise over the will, the personal representative, or how assets should be distributed.
Debts Get Paid Before Heirs Do
The estate must pay its debts before heirs receive anything. The personal representative is responsible for notifying known creditors directly and publishing a notice for unknown creditors.
Creditors who receive proper notice have four months from the date of first publication to file a claim.15Justia. Alaska Code 13.16.460 – Limitations on Presentation of Claims If no notice is published, creditors have up to three years from the date of death.16Alaska Court System. Debts and Creditors Publishing notice promptly is what limits the estate’s exposure.
Debts are paid in a priority order: funeral expenses and costs of administering the estate first, then secured debts such as mortgages, then unsecured debts like credit cards and medical bills. If assets run out before lower-priority debts are covered, those debts go partially or entirely unpaid and the estate is declared insolvent. Heirs are generally not personally liable for the deceased person’s debts unless they co-signed on a loan or otherwise took on legal responsibility.
Some assets are shielded from estate creditors entirely. Life insurance proceeds payable to a named beneficiary rather than the estate, retirement accounts with designated beneficiaries, and properly structured trusts typically cannot be reached.
Medicaid Can Reduce What’s Left
Federal law requires every state, including Alaska, to seek reimbursement from a deceased person’s estate for Medicaid-funded long-term care. This covers nursing home care, home- and community-based services, and related hospital and prescription costs.17Legal Information Institute. 7 AAC 160.210 – Estate Recovery Alaska will not pursue a claim if the recovery amount is less than $10,000, or if a surviving spouse, minor child, or disabled child survives the recipient.
This catches many families off guard. A parent who received Medicaid-funded nursing home care may leave an estate that looks like it should pass to the children, only for the state to file a claim that reduces or eliminates what remains. Planning with trusts or other strategies can protect assets, but it has to happen well before Medicaid benefits begin.
Challenging a Will
Interested parties can challenge a will’s validity in Alaska probate court. The most common grounds are that the maker lacked mental capacity when signing, that someone pressured or manipulated them, or that the document was forged or improperly executed. These cases typically rely on medical records, witness testimony, and sometimes expert evaluations.
Timing is strict. A proceeding to contest an informally probated will must be filed within 12 months of the informal probate or within three years of the death, whichever comes later.18Justia. Alaska Code 13.16.040 – Probate, Testacy, and Appointment Proceedings; Ultimate Time Limit Past that window, the court won’t hear the challenge regardless of its merits.
Heirs can also challenge the personal representative’s conduct. If the representative is mismanaging assets, failing to pay debts in the right priority, or refusing to provide accountings, beneficiaries can petition the court for removal. Mediation is available as an alternative to litigation and can resolve disputes faster and more cheaply, with formal court proceedings as the fallback.
Federal Estate Tax
Alaska imposes no state death tax, but the federal estate tax reaches large estates. For 2026, estates valued above $15 million must file a federal estate tax return (Form 706), with a top rate of 40% on amounts above the exemption.2Internal Revenue Service. Estate Tax Married couples can effectively double the exemption to $30 million through portability, where the surviving spouse claims the unused portion of the deceased spouse’s exemption.
The filing deadline is nine months after the date of death, with an automatic six-month extension available by filing Form 4768.19Internal Revenue Service. Instructions for Form 706 Even when no tax is owed, filing may still be necessary to elect portability. Estates well below the $15 million threshold don’t need to file.
The annual gift tax exclusion for 2026 is $19,000 per recipient, which can be given to any number of people each year without touching the lifetime estate tax exemption.20Internal Revenue Service. What’s New – Estate and Gift Tax
