A will in contemplation of marriage is a will that names your intended spouse by full legal name and expressly states that the document should remain in effect after the wedding takes place. That language matters because in most states, marrying after you sign a will gives your new spouse the right to claim a share of your estate as an “omitted spouse,” regardless of what the will actually says. The contemplation clause is the cleanest way to shut down that claim and keep the estate plan you already have.
Why Marriage Disrupts an Existing Will
Getting married after you sign a will does not automatically rewrite the document, but it changes who can take from your estate. Under the framework used by most states, modeled on the Uniform Probate Code, a spouse you married after signing qualifies as an omitted spouse and can claim the share they would have received if you had died without a will at all. That intestate share commonly runs from one-third to one-half of the estate, depending on whether you have children and which state’s law applies.
A smaller number of states take the older common-law approach, tracing back to the Wills Act 1837, and revoke the entire will on marriage. If that happens, the will is treated as if it never existed and everything passes under intestacy rules. The practical result in either system is the same: the people you intended to inherit, whether siblings, friends, children from a prior relationship, or charities, can be partially or completely displaced by your new spouse.
There are three recognized ways to prevent the omitted-spouse claim. The will can be made in contemplation of marriage to that specific person. It can expressly state that it remains effective despite any future marriage. Or you can show that you provided for your spouse outside the will and meant those transfers to replace a testamentary share. The first option is the most reliable because the proof lives inside the will itself; the other two often invite outside evidence and argument.
What the Clause Must Say
Two elements are non-negotiable. First, the clause has to identify your intended spouse by full legal name. A reference to “my future spouse” or “whoever I may marry” will not satisfy the requirement, because courts look for the specific person contemplated rather than a general openness to marrying someone eventually. Second, the clause has to make clear you want the will to stay in effect after the wedding. Both pieces usually appear in a single sentence.
A typical clause reads: “This will is made in contemplation of my marriage to [full legal name], and I intend for it to remain effective after our marriage.” No magic wording is required, but both the identification and the intent must be unambiguous. If a court cannot tell who you planned to marry or whether you wanted the will to survive the ceremony, the clause can be set aside and your spouse treated as omitted anyway.
One point surprises people: the will does not have to leave your future spouse anything for the contemplation clause to work. The clause tells the court you knew about the upcoming marriage when you signed, so the omitted-spouse protection is unnecessary. In theory, you could leave your entire estate to someone else. Whether your spouse could still claim a share on other grounds is a separate question, discussed below.
What the Clause Does Not Do
A contemplation clause blocks the omitted-spouse claim. It does not do three other things people often assume it does.
It does not override your state’s elective share. Elective-share statutes give a surviving spouse the right to take a minimum percentage of the estate, commonly one-third to one-half, no matter what the will says. The contemplation clause has no effect on that floor. The usual way to address the elective share is a prenuptial agreement that waives it, and courts enforce those waivers only when the agreement was signed voluntarily, with full financial disclosure, and properly notarized. Where a prenup and a will conflict, the probate court will generally enforce the prenup, because the prenup is a contract between two people while the will is a one-sided document.
It does not reach assets that bypass probate. Your will only controls property that passes through probate. Retirement accounts, life insurance, and bank or investment accounts with payable-on-death or transfer-on-death designations go to whoever is named on the form. Jointly held real estate or accounts with right of survivorship pass automatically to the surviving owner. For most employer-sponsored retirement plans, federal law actually requires your spouse to be the beneficiary after marriage unless they sign a written waiver. If you draft a careful will leaving your 401(k) proceeds to your children and never update the beneficiary form, the form wins. Lining up beneficiary designations with your will is a separate task, and the contemplation clause does nothing to help.
It does not plan for divorce. If you later divorce, most states automatically revoke any provisions in the will that benefit the former spouse, treating the ex as if they had died before you. That is a safety net, not a strategy. After a divorce, write a new will rather than leaning on the statute to tidy up the old one.
Signing the Will So the Clause Holds Up
A clause that says the right things is worthless if the will was not executed correctly. Standard requirements call for the will to be in writing, signed by you, and signed by at least two adult witnesses of sound mind who watched you sign or heard you acknowledge your signature. The witnesses should be disinterested, meaning they take nothing under the will. An interested witness does not automatically void the document, but it opens the door to exactly the kind of challenge the contemplation clause is meant to prevent.
Attach a self-proving affidavit if your state allows one. It is a sworn statement, signed by you and your witnesses in front of a notary, confirming the will was executed voluntarily and that everyone was present. Without it, the probate court may need to track your witnesses down to verify the signing, which causes delays and becomes impossible if a witness has died or moved. With it, the court can accept the will without live testimony.
Store the signed original somewhere your executor can actually get to it. A fireproof home safe is fine as long as the executor knows the combination. Some states let you deposit the will with the local probate court for a small fee. A bank safe deposit box is a poor choice unless your executor is a co-holder, because access after death can require the very court order the will is supposed to make easier.
If the Wedding Does Not Happen
If the marriage never takes place, the contemplation clause becomes irrelevant but does not invalidate the will. The clause exists only to protect against the legal consequences of marriage. No marriage means no omitted-spouse claim and no revocation on marriage, so the will stands on its own terms. That said, a will referring to a wedding to someone you are no longer marrying is confusing on its face and invites argument during probate. If the engagement ends, replace the will.
The same logic applies in reverse once you are actually married. A contemplation clause tied to the right person, signed while you were engaged, carries you through the wedding without the omitted-spouse problem. From there, your estate plan should be reviewed against your new household, your beneficiary designations, and any prenuptial agreement you signed, so the pieces line up rather than fight each other.
