If you are considering a prenuptial agreement or already have one in place, you may wonder how long it remains effective.
Does it expire after a certain number of years?
Does it become invalid after children are born?
Can a long marriage make a prenup unenforceable?
In most cases, a prenuptial agreement remains valid throughout the marriage unless it is modified, revoked, or found to be unenforceable under the law. There is generally no automatic expiration date simply because time has passed.
However, the answer depends on the specific language of the agreement and the circumstances surrounding it.
Understanding how prenuptial agreements work over time can help you make informed decisions before and during your marriage. Our Salt Lake City family lawyers can answer any questions you may have.
Does a Prenuptial Agreement Expire?
Generally, no.
Most prenuptial agreements do not automatically expire after a certain number of years.
Instead, premarital agreements remain in effect until one of several things happens:
- The marriage ends through divorce.
- One spouse passes away, if the agreement addresses those issues.
- The agreement is modified by the parties.
- The agreement is revoked.
- A court determines that all or part of the agreement should not be enforced.
Simply staying married for five, ten, or twenty years does not usually cause a prenup to expire.

Can a Prenup Include an Expiration Date?
Yes.
Some couples choose to include what is commonly referred to as a “sunset provision.”
A sunset provision states that certain parts of the agreement, or sometimes the entire agreement, will expire after a specific event or period of time.
For example, a prenup might provide that certain provisions end after:
- Ten years of marriage
- Fifteen years of marriage
- The birth of children
- Another agreed-upon event
Not every prenuptial agreement contains this type of provision.
If the agreement does not include an expiration clause, it generally continues according to its stated terms.
A Calmer, Clearer Way Through Divorce
Can a Prenup Be Changed After Marriage?
Yes.
Life circumstances often change after a couple gets married.
For example:
- One spouse starts a business.
- The couple has children.
- They purchase significant real estate.
- Their financial situation changes dramatically.
If both spouses agree, they may decide to modify certain financial arrangements.
Because a prenuptial agreement is signed before marriage, any changes made afterward generally require a separate legal agreement.
Those changes should be prepared carefully to ensure they comply with applicable legal requirements.
What If We Never Look at It Again?
Many couples sign a prenuptial agreement and never think about it again unless they later face divorce or another significant legal event.
That is perfectly normal.
A properly prepared agreement often remains in the background for many years without requiring any additional action.
However, major financial changes may make it worthwhile to review the agreement periodically to ensure it still reflects the couple’s goals.
Can a Court Refuse to Enforce a Prenup?
Sometimes.
The fact that an agreement has existed for many years does not automatically guarantee that every provision will be enforced.
If a dispute arises, the court may evaluate issues such as:
- Whether the agreement was entered into voluntarily
- Whether there was appropriate financial disclosure
- Whether legal requirements were satisfied
- Whether the agreement remains enforceable under applicable law
Each case depends on its own facts.
Simply being married for a long time does not automatically invalidate a prenuptial agreement.
Does Having Children End a Prenup?
Generally, no.
Having children does not automatically cancel a prenuptial agreement.
However, children often change a family’s financial priorities.
While a prenup may address financial matters between spouses, issues involving child custody and child support are generally determined according to the law and the child’s best interests.
Parents cannot simply decide in advance how future custody or child support issues will be handled if doing so conflicts with applicable law.
What if Our Financial Situation Changes?
Many couples experience major financial changes during marriage.
Examples include:
- Buying a home
- Selling a business
- Receiving an inheritance
- Building retirement savings
- Starting a company
- Accumulating significant investments
These events do not automatically invalidate an existing prenuptial agreement.
However, they may prompt a couple to review whether the agreement continues to meet their needs.
Can You Ignore a Prenuptial Agreement?
No.
If a valid prenuptial agreement exists, it should be considered during a divorce or other legal proceeding in which it may apply.
Ignoring the agreement or assuming it no longer matters because many years have passed can create unnecessary legal complications.
Having the agreement reviewed early in the process allows both parties to better understand their rights and obligations.
Common Misconceptions About Prenuptial Agreements
People often believe:
- Every prenup expires after a certain number of years.
- A long marriage automatically cancels the agreement.
- Having children makes the prenup invalid.
- A prenup never changes once it is signed.
These assumptions are not generally accurate.
The answer depends on the specific language of the agreement and the applicable law.
Why Periodic Review Can Be Helpful
Although many prenuptial agreements remain effective for decades, reviewing the agreement from time to time can still be beneficial.
Major life events often change a family’s financial picture.
Reviewing the agreement after significant changes allows couples to determine whether it continues to reflect their intentions.
Many people view this review as part of responsible long-term financial planning rather than anticipating divorce.
Planning for the Future
A prenuptial agreement is designed to provide clarity.
It allows couples to make thoughtful financial decisions before marriage instead of leaving every issue to future uncertainty.
When properly prepared, a prenup can continue serving that purpose throughout the marriage unless both parties choose to modify it or another legal issue affects its enforceability.
Understanding how long a prenuptial agreement remains valid helps couples make informed decisions both before and after they marry.
