How long does alimony last in Pennsylvania?

Last updated October 4, 2026.

Pennsylvania has no formula for how long alimony lasts. When a court finds alimony necessary, it sets the duration as a "definite or an indefinite period of time which is reasonable under the circumstances," after weighing the factors in 23 Pa.C.S. 3701(b), such as the length of the marriage, each spouse's earning capacity, age and health, and the time needed to get training for appropriate work (3701(c)). Alimony ends on the recipient's remarriage (3701(e)) or death (3707), is barred by cohabitation as defined in 3706, and can be modified for substantial and continuing changes.

Agreed alimony works differently: if the spouses set alimony in a written agreement, the court generally cannot modify it unless the agreement allows it (23 Pa.C.S. 3105(c)). For our divorce work in Media, see our family law page.

How does a court decide the length, step by step?

1. Claim it in time. Alimony must be raised in the divorce pleadings; the notice to defend warns that a claim not filed before the decree may be lost (Pa.R.C.P. 1920.71).
2. Divide the property first. One factor is whether the spouse seeking alimony lacks enough property, including property received in equitable distribution, to provide for reasonable needs (3701(b)(16)). That is why alimony and property are usually heard together; see how property is divided.
3. Decide whether alimony is necessary. The court may allow alimony "only if it finds that alimony is necessary" (3701(a)).
4. Weigh the factors. The court considers all relevant factors, including the 17 listed in 3701(b), in deciding the nature, amount, duration and manner of payment.
5. Set the duration. A definite period (for example, a set number of years) or an indefinite period, whichever is reasonable (3701(c)).
6. State reasons. The order must give the reasons for the award or denial and the amount (3701(d)).

In Delaware County, the county handbook says the divorce hearing officer addresses alimony at the equitable distribution hearing, and a spouse who disagrees can ask for a de novo trial before a judge within the time stated in the report.

Which factors bear most on duration?

The other listed factors are sources of income including benefits, expectancies and inheritances, contributions to the other's education or earning power, assets and liabilities, property brought to the marriage, homemaker contributions and tax consequences (3701(b)).

What ends or changes alimony?

• Remarriage of the recipient. It terminates the award (3701(e)).
• Cohabitation. As the statute is written, no one is entitled to alimony who, after the divorce, has entered into cohabitation with a person of the opposite sex who is not a family member within the degrees of consanguinity (3706).
• Death of the recipient. The right to receive alimony ends (3707).
• Death of the payer. The obligation ends unless an agreement or court order says otherwise (3707).
• Changed circumstances. A court-ordered award is subject to further order on substantial and continuing changes for either party, and may be modified, suspended, terminated or reinstated, but the change applies only to payments that come due after the petition (3701(e)).
• The end date. A definite-term award ends when the term runs out.

Alimony is different from spousal support and alimony pendente lite, which come before the decree and follow the support guidelines; see spousal support, APL and alimony compared.

Should alimony be agreed in a settlement instead?

Many couples settle alimony in a written agreement rather than leaving it to a hearing officer or judge, and the choice has lasting effects; agreements are covered in whether a prenup or postnup is enforceable. A court-ordered award stays open to modification whenever either party's circumstances change in a substantial and continuing way (3701(e)). An agreed award is the opposite by default: in the absence of a specific provision to the contrary, the alimony terms of an agreement are not subject to modification by the court (3105(c)). The agreement can still be enforced with the same remedies the court uses for its own orders, whether or not it was merged into the decree (3105(a)).

That makes the drafting important. A settlement can say whether alimony may be modified, what happens if the recipient cohabits or remarries, whether payments continue if the payer dies and whether life insurance secures them. Leaving those points out means the statutory defaults apply. The duration of the marriage, measured to the date of final separation, is often the starting point of negotiation, so pin down that date; see why the date of separation matters.

How is alimony paid and enforced?

When the court so orders, alimony is paid through the domestic relations section, which keeps the record of payments, distributes them and notifies the court when the payer is 30 days behind (23 Pa.C.S. 3704). If arrears build up, the court may, after a hearing, enter judgment, seize property or collect rents, attach no more than 50 percent of wages, award interest on unpaid installments, require security for future payments, award counsel fees and, for willful noncompliance, hold the payer in civil contempt with commitment for up to six months (3703). In Delaware County, Domestic Relations is in the Curran Building in Media; see what happens at a support conference in Delaware County for how that office works.

What changes the answer?

• An agreement. Alimony terms in an agreement cannot be modified by the court absent a specific provision allowing it (3105(c)), though they can be enforced with the same remedies as an order (3105(a)).
• Abuse. Post-separation misconduct is ignored for alimony except abuse of one party by the other (3701(b)(14)).
• Security for payments. The court can require life insurance or a lien to secure alimony (3502(b) and (d)).
• Tax treatment. Tax ramifications are a listed factor (3701(b)(15)).
• A move to another state. Alimony decrees from other states can be registered and enforced here (3705).

For example: a 22-year marriage and a return to work

Here is a hypothetical. A couple in Media divorce after 22 years. One spouse left a nursing career to raise the children and has not worked in 15 years; the other is a manager. After the property division, the lower-earning spouse receives half the equity in the house but little else that produces income.

The hearing officer finds alimony necessary. Weighing the long marriage, the earnings gap, the time needed to renew a nursing license and the property received, the hearing officer might recommend alimony for a set number of years tied to retraining, with a step-down as income resumes, and states the reasons. If the recipient later remarries, the award ends; if the payer is laid off, the payer can petition to modify, but only for payments that come due after the petition. This example only illustrates the statute; it is not a prediction of any award.

What mistakes do spouses make about alimony?

• Not claiming it before the decree. The right can be lost (Rule 1920.71).
• Waiting to file a modification petition. Changes apply only to payments after the petition (3701(e)).
• Signing an agreement without a modification clause. Agreed alimony is not modifiable unless the agreement says so (3105(c)).
• Not planning for the payer's death. The obligation ends unless an agreement or order provides otherwise, so ask about life insurance (3707; 3502(d)).
• Assuming alimony is permanent. Duration is set case by case and may be definite.
• Ignoring the property side. More property can mean less need for alimony (3701(b)(16)).

What should I do this week?

1. Confirm that alimony is claimed in your divorce pleadings.
2. Gather proof of income, health and work history for both spouses.
3. Estimate the time and cost of any training needed to return to work.
4. List your monthly needs after the divorce.
5. If settling, decide whether alimony should be modifiable and what happens on the payer's death.
6. Book a consultation to plan your position on duration.

Frequently asked questions

Is there a rule like one year of alimony for every three years of marriage?

No such ratio appears in the statute. The court sets a reasonable definite or indefinite period after weighing the factors (3701(c)).

Can alimony be increased later?

A court-ordered award can be modified up or down on substantial and continuing changed circumstances (3701(e)). Agreed alimony generally cannot be changed unless the agreement allows it (3105(c)).

Does alimony stop if my former spouse moves in with someone?

Section 3706 bars alimony for a petitioner who, after the divorce, cohabits with a person of the opposite sex who is not a family member. Whether a living arrangement meets that definition is decided on the facts.

Can alimony be awarded to either spouse?

Yes. The statute allows alimony "to either party" when the court finds it necessary (3701(a)), regardless of gender, and the same factors apply.

Can the court refuse alimony entirely?

Yes. If the court does not find alimony necessary, for example because the property each spouse receives and their earning capacities cover reasonable needs, it denies the claim and must state its reasons (3701(a) and (d)).

What happens to alimony if I die?

The obligation ends unless an agreement or court order provides otherwise (3707), which is why life insurance is often part of the order (3502(d)). Your estate plan should match; see our wills and estates page.

Is alimony decided at the same time as the divorce?

Usually, with property; the decree can come first only if the court allows bifurcation. See how long a divorce takes. The types of divorce are described on our divorce page.
