Joint Tenancy in Hawaii: Rules, Severance, and Tax Pitfalls

Joint tenancy in Hawaii is a form of co-ownership that gives each owner an undivided interest in the whole property and passes a deceased owner’s share automatically to the survivors, but it only exists when the deed says so in unmistakable terms. Hawaii Revised Statutes 509-1 treats every co-owned property as a tenancy in common by default. If the deed does not expressly state that the grantees take title as joint tenants with the right of survivorship, each owner instead holds a separate, inheritable share and no survivorship applies.¹

Creating a Joint Tenancy

The deed has to do the work. Vague language will not create a joint tenancy in Hawaii; the intent and the survivorship right must appear on the face of the instrument.¹

Hawaii simplifies one older obstacle. At common law, an owner who wanted to add someone as a joint tenant had to first deed the property to an intermediary, who would then deed it back to both parties. HRS 509-2 removes that step. You can convey property directly to yourself and another person as joint tenants, or convert an existing tenancy in common into a joint tenancy, without routing the deed through a third party.²

The deed must be signed by the grantor, acknowledged before a notary, and recorded with the Hawaii Bureau of Conveyances. Recording is not just administrative. Under HRS 502-83, an unrecorded deed is void against any later buyer, lender, or lessee who acts in good faith, pays value, and records first.³ Hawaii runs two parallel recording systems: the Land Court system for properties with a Certificate of Title, and the Regular System for everything else.⁴

Adding someone to a deed can also trigger Hawaii’s conveyance tax under HRS Chapter 247 when consideration is involved. Rates run from $0.10 per $100 of value for properties under $600,000 up to $1.00 per $100 for properties valued at $10 million or more, with higher brackets applying when the buyer of a single-family residence or condo is ineligible for a county homeowner’s exemption.⁵ Factor that into the cost of setting up or restructuring co-ownership.

Joint Tenancy or Tenancy by the Entirety

Hawaii recognizes a related co-ownership form for married couples, civil union partners, and reciprocal beneficiaries: tenancy by the entirety. Both forms carry survivorship. The differences matter.

A joint tenant can independently transfer or encumber their share, and any one co-owner can force a partition sale. Tenants by the entirety generally cannot sell, mortgage, or partition without the other spouse’s or partner’s consent. That restriction produces a real creditor shield: a creditor holding a judgment against only one spouse typically cannot force a sale of entirety property to collect, while a creditor of a single joint tenant may be able to reach that tenant’s interest.

HRS 509-2 extends tenancy by the entirety to civil union partners and reciprocal beneficiaries, not just married couples.² For anyone in one of those relationships, choosing joint tenancy over tenancy by the entirety gives up creditor protection for no gain in flexibility that matters at death, because both carry survivorship.

What Joint Tenants Can and Cannot Do

Survivorship

When one joint tenant dies, that owner’s interest vanishes from the estate and passes to the surviving tenant or tenants. There is no probate for the property, and the deceased owner’s will has no effect on it, even if the will says otherwise. That is the point of the arrangement for people who want a clean transfer, and it is also the trap for anyone who assumed their share would follow their estate plan.

Possession and Use

Every joint tenant has the right to possess and use the entire property. Legally, there are no ownership percentages in a joint tenancy; each person holds an undivided interest in the whole, regardless of who paid what.

One tenant cannot unilaterally rent the property out, build on it, or restrict another tenant’s access. If one tenant collects rent from a third party, the others may have a right to their proportional share of that income.

Expenses

Joint tenants share responsibility for property taxes, mortgage payments, insurance, and necessary repairs. Hawaii law does not spell out a formula, but courts generally expect proportional contributions. When one tenant pays more than their share, that tenant can seek reimbursement from the others, often through a partition action where the court accounts for contributions before dividing proceeds.

Creditor Exposure

A creditor holding a judgment against one joint tenant can place a lien on that tenant’s interest and potentially force a sale of that interest. This is the sharpest divergence from tenancy by the entirety, where a single spouse’s creditor generally cannot reach the property.

Timing is decisive. If the creditor forces a sale of the debtor-tenant’s interest, the joint tenancy is severed and the buyer becomes a tenant in common with the remaining owners. If the debtor-tenant dies before the creditor completes a sale, the right of survivorship kicks in, the debtor’s interest disappears, and the surviving tenant takes the property free of the deceased tenant’s personal debts. One person’s financial trouble can drag the entire property into litigation even if the other owners are debt-free.

Severing or Ending the Joint Tenancy

Voluntary Severance

Any joint tenant can sever the joint tenancy unilaterally, without the other tenants’ consent, by conveying their interest. That can be a transfer to a third party or a conveyance from oneself to oneself as a tenant in common. Because Hawaii has eliminated the straw man requirement, the self-conveyance can be executed directly.² Once recorded, the severed share becomes a tenancy in common with the remaining owners, and survivorship no longer applies to it.

Joint tenants can also sever by mutual agreement, using a new deed to convert their ownership to a tenancy in common or to divide the property. All parties must sign, and the deed must be recorded to be effective against third parties.³

Partition

When co-owners cannot agree, any joint tenant (or tenant in common) can file a partition action in the circuit court where the property is located. Under HRS 668-1, the court can physically divide the property among the owners according to their interests, or order a sale and distribute the proceeds if a physical division would cause “great prejudice” to the owners.⁶ Houses and condos rarely divide meaningfully, so residential partition actions almost always end in a court-ordered sale. The court can account for unequal contributions before splitting the proceeds. Partition is expensive and adversarial, which is why a written co-ownership agreement at the outset is the cheaper path when disagreement is possible.

Watch the Mortgage

Severing joint tenancy on mortgaged property does not automatically trigger the loan’s due-on-sale clause in most residential situations. The federal Garn-St. Germain Act prohibits lenders from accelerating a loan secured by residential property with fewer than five units when the transfer occurs by operation of law on the death of a joint tenant, when a spouse or child becomes an owner, or in certain other protected scenarios.⁷ A voluntary transfer to an unrelated third party is not protected, and the lender could demand full repayment. Confirm with the lender before restructuring.

Tax Pitfalls

Gift Tax When You Add Someone

Adding someone to a deed as a joint tenant is a transfer of a property interest. The IRS treats it as a gift when the new co-owner does not pay fair market value for their share. Add an adult child as a joint tenant on a home worth $500,000, and you have made a gift of roughly $250,000. The federal annual gift tax exclusion for 2026 is $19,000 per recipient, and anything above that reduces the lifetime estate and gift tax exemption, which stands at $15,000,000 for 2026.⁸ IRS Form 709 must be filed in any year you make gifts exceeding the annual exclusion, even if no tax is owed. Married couples can elect gift splitting to double the tax-free amount to $38,000 per recipient.

Only a Partial Step-Up in Basis

Joint tenancy creates a partial step-up in basis at death, not a full one. When one joint tenant dies, only the decedent’s share of the property receives a new basis equal to its fair market value at the date of death. The surviving tenant’s basis in their own share stays the same.⁹ This bites when the surviving owner eventually sells. Property held instead through a trust or passed entirely through an estate can, in some structures, receive a full step-up and eliminate that gain. This is one of the most overlooked costs of joint tenancy for estate planning.

Conveyance Tax on Severance

Any deed transferring an interest in Hawaii real property can trigger the state conveyance tax under HRS Chapter 247. Severing a joint tenancy by deeding your interest to yourself as a tenant in common, or to a third party, may fall within that tax depending on whether consideration is involved. Rates range from 0.10% to 1.25% of the property’s value.⁵ Before recording a severance deed, confirm whether an exemption applies.

Where Joint Tenancy Backfires in Estate Planning

The right of survivorship overrides a will. If your will leaves everything to your children but you hold property in joint tenancy with a sibling, your children get nothing from that property. The sibling takes full ownership the moment you die, regardless of what your estate plan says.

Joint tenancy also creates an irrevocable transfer of control during your lifetime. Once you add someone, you cannot sell, refinance, or mortgage without their cooperation. If the relationship breaks down, the options are negotiation, a buyout, or a partition action. A revocable living trust, by contrast, lets the grantor retain full control during life while still avoiding probate at death.

For Hawaii residents, the availability of tenancy by the entirety for married couples, civil union partners, and reciprocal beneficiaries adds creditor protection that joint tenancy does not offer. Picking joint tenancy when entirety is available leaves the property exposed to one partner’s individual creditors. On a primary residence with significant equity, that is a real cost worth weighing with a Hawaii estate planning attorney before the deed is signed.
