Community Property Brought Into a Common Law State

A couple who spent fifteen years in a community property state and then moved east owns two categories of property whether or not anybody has ever said so. The distinction survives the move, it survives decades of ordinary financial life, and it emerges at divorce, at death and at the point a long-held asset is sold.

The two systems

Community property states treat most marital acquisitions as jointly owned. Earnings during marriage and what is bought with them belong equally to both spouses from the moment of acquisition.

Common law states follow title. Property belongs to whoever acquired it, with protections for the other spouse operating at divorce and at death rather than during the marriage.

Gifts and inheritances stay separate in both. As does property owned before marriage, subject to rules about commingling and about increases in value.

Nine states use the community system. A substantial share of the population lives in them at some point, which is why the question arises so often.

And character attaches at acquisition. Which is the principle that makes everything else in this article follow.

What a move does

It does not reclassify existing assets. Property acquired while domiciled in a community property state remains community property afterward.

It changes the rules for future acquisitions. Assets acquired after the move are characterized under the new state's law.

So the marriage holds two categories. Separated by the date of the move and by which state the couple was domiciled in when each asset was acquired.

Most receiving states recognize the character. Several have adopted uniform legislation dealing specifically with community property held at death.

And domicile is what counts. Not where an asset was purchased or where an account is held, but where the couple was domiciled, which is the analysis in what a domicile audit examines.

Why it matters at death

Each spouse devises only their half. A will purporting to leave the whole of a community asset to somebody else operates only on the testator's own interest.

The survivor already owns the other half. It does not pass through the estate at all and is not subject to the will or to intestacy.

The elective share interacts. A surviving spouse's statutory claim against the estate is calculated differently where community property is involved, and states handle the interaction in different ways.

Real property still follows the situs. Land is governed where it sits regardless of character, as set out in real property outside the state of death.

And the basis adjustment applies to the whole. Community property receives an adjustment on both halves at the first death, which is frequently the largest consequence of the entire question.

The tracing problem

Records decay. Statements are discarded, accounts are consolidated and institutions purge history, so the evidence of when and where an asset was acquired thins each year.

Commingling obscures character. Community funds mixed with separate funds in one account create a tracing exercise that can be expensive and inconclusive.

Refinancing and rollovers complicate it further. An asset sold and reinvested generally keeps its character, and proving the chain requires the intermediate records.

Retirement accounts need particular care. Contributions made in different states carry different characters within a single account, and the split has to be reconstructed from contribution history.

So the record is the asset. Preserving evidence of character is what makes the rights real, and its absence is why many claims are settled rather than proved.

What to do about it

Document the character now. A schedule of assets identifying which were acquired while domiciled in a community property state, prepared while the records still exist.

Keep community assets segregated. Not mixing them with post-move acquisitions preserves the distinction without any tracing at all.

Review the will and the trust. Documents drafted after the move frequently assume everything is separate property, and their provisions may not operate as intended.

Consider a written agreement. Spouses can generally agree on the character of their property, and a clear agreement removes the tracing burden entirely.

And take the basis point seriously. Where a substantial appreciated asset is community property, the tax consequence of establishing that at the first death is frequently worth more than the entire cost of documenting it.

The reason this issue is so consistently missed is that nothing prompts it. A couple moving states updates a driver's license, registers to vote and perhaps has a will redrafted, and none of those steps raises the question of how existing assets are characterized. The lawyer drafting the new will works from the new state's framework, the couple does not mention a move that happened years ago, and the assumption that everything is separate property goes unexamined until it cannot be.

By the time it is examined — at a divorce, at a first death, or when an appreciated asset is being sold — the records needed to prove character are frequently gone. The claim then depends on inference from contribution dates and employment history, which is possible and expensive, and which produces a negotiated answer rather than a certain one.

The remedy is unusually simple relative to the stakes. A single schedule, prepared once, listing significant assets and identifying which were acquired while the couple was domiciled in a community property state, with supporting documents attached, resolves the question permanently. It takes an afternoon and it should be prepared in the year of the move, when the records are still at hand and the dates are still remembered.

For anyone advising a couple who has moved from one of the nine states, the question belongs in the first meeting, phrased plainly: where was the couple living when each of these was acquired. The answer shapes the will, the trust, the beneficiary designations and the tax planning, and it is the one piece of information that cannot be reconstructed later if nobody asks for it now.

Two related points complete the picture. The first is that the character question does not disappear if the couple later moves back, or moves to a third state; each period of domicile characterizes what was acquired during it, so a family that has lived in several states may hold assets in several categories. The second is that the analysis interacts with everything else in a cross-border estate. Real property is still governed by the state where it sits regardless of character, as set out in real property outside the state of death, and where there is no will the intestacy schemes described in which state's intestacy rules apply operate on the deceased spouse's half rather than on the whole of a community asset.

None of that makes the issue difficult to manage. It makes it one that has to be identified, because every one of these consequences follows automatically from facts that were settled years earlier and that nobody is currently tracking. The identification is the work; the rest is documentation.
