Ohio Marital Property: Common Law Rules, Dower Rights, and Estate Planning

Ohio is a common law property state, not a community property state. This distinction shapes everything about how married couples own, transfer, and inherit assets — and it creates planning traps that community property transplants from California, Texas, or Washington rarely see coming.

Common Law vs. Community Property: What It Means

In a community property state, most assets acquired during marriage are automatically owned 50/50 by both spouses, regardless of whose name is on the title. In Ohio's common law system, title controls everything. The person whose name is on the deed, account, or title is the legal owner.

If one spouse earns income and deposits it into a bank account solely in their name, that account belongs to that spouse alone — even though the income was earned during the marriage. The other spouse has no automatic ownership claim to it during the marriage (divorce law applies different equitable distribution rules, but estate planning operates on title).

This means a married Ohio resident can accumulate assets entirely in their own name, with no co-ownership by their spouse, simply by titling everything individually.

Dower Rights: Ohio's Safety Net

To prevent one spouse from completely cutting the other out, Ohio maintains one of the nation's last statutory dower provisions under R.C. 2103.02.

Dower gives a surviving spouse a one-third life estate in any real property owned by the other spouse at any point during the marriage — even if the surviving spouse was never on the deed.

What Dower Means in Practice

• A married person cannot sell, mortgage, or place a Transfer on Death Designation Affidavit on real property without the other spouse's notarized signature releasing dower
• Dower survives divorce only through a specific written waiver — it is not automatically terminated by separation
• Dower applies to property the spouse owned at any time during the marriage, not just property owned at death

This creates a direct impact on estate planning. If you record a TOD Designation Affidavit on your house without your spouse's dower release signature, the affidavit is defective. The property could end up in probate despite your planning efforts.

Spousal Protections Beyond Dower

Ohio provides several additional protections for surviving spouses that operate independently of the will:

Support allowance (R.C. 2106.13). The surviving spouse has a priority claim of $40,000 from the probate estate. If there are no minor children, or if all minor children are also the children of the surviving spouse, the full $40,000 goes to the spouse. If there are minor children from another relationship, the court divides the allowance equitably.

Vehicle selection (R.C. 2106.18). A surviving spouse can transfer the deceased spouse's sole-titled vehicles into their own name, up to a combined appraised value of $65,000. These vehicles are excluded from the estate inventory. Selecting one vehicle does not reduce the $40,000 support allowance (clarified by House Bill 7, effective August 2021).

Mansion house right (R.C. 2106.15). The surviving spouse can remain in the marital home rent-free for one year after the date of death. If the estate must sell the home to pay debts, the spouse must receive cash equal to the fair rental value for the remaining portion of the year.

Elective share. A surviving spouse can "take against the will" and receive one-half of the net probate estate (if zero or one child survives) or one-third (if two or more children survive), regardless of what the will says.

The Community Property Transplant Problem

Couples who move to Ohio from a community property state face a specific tax disadvantage. In community property states, when one spouse dies, the surviving spouse receives a full stepped-up tax basis on all community property — both halves. This eliminates capital gains tax on appreciated assets.

In Ohio, only the deceased spouse's half of jointly owned property gets a stepped-up basis. The surviving spouse's half retains its original cost basis, meaning future sale proceeds above that basis are taxable.

Ohio has adopted the Uniform Disposition of Community Property Rights at Death Act, which preserves the community property character of assets that were community property before the move. But it does not create new community property treatment for assets acquired after arriving in Ohio.

For couples with significant appreciated assets, this basis difference can cost tens of thousands in capital gains taxes. Some couples establish a community property trust in a state like Kentucky (which enacted elective community property trust legislation) to preserve the double step-up while living in Ohio.

What This Means for Your Estate Plan

In Ohio, your estate plan must account for the title-based ownership system:

• Make sure both spouses know which assets are in whose name
• Get dower releases on all real estate TOD designations
• Understand that the elective share only covers probate assets — if one spouse moves everything into TOD and POD designations, the other spouse's elective share may be minimal
• Couples relocating from community property states should evaluate the cost-basis impact before retitling assets
