If you are considering a divorce or are already in a separation situation, the desire for financial clarity is often front and center. You may be asking yourself: Is there still a right to alimony after the divorce? How long does this right last? And what happens if the marriage ended because of infidelity, does the affected spouse then receive more alimony?
Under Swiss law, the rule is clear: post-divorce alimony is not a punishment and not a moral compensation. Rather, it is intended to provide support where the marriage has caused economic disadvantages that cannot immediately be borne independently. Therefore, the focus is less on the reasons for the separation and much more on whether, and to what extent, independent financial self-sufficiency after the marriage can reasonably be expected.
Alimony and Child Support: A Clear Distinction
In everyday language, people often speak broadly of “alimony.” Legally, however, it is essential to distinguish between the two. Child support serves the welfare of the child and is regulated independently of the reasons why the parents separate. Its purpose is to ensure that the child’s needs are met.
Alimony, by contrast, concerns the spouses themselves. Here, a distinction is made between support during separation, while the marriage still legally exists, and post-divorce alimony after the divorce. In the following, we focus on post-divorce alimony.
The Basic Principle After Divorce: Self-Sufficiency, but Not at Any Price
Swiss divorce law generally aims for both spouses to become as independent as possible again after the divorce. This means that post-divorce alimony is not automatically owed. A claim for alimony exists in particular if one person cannot finance their “appropriate maintenance” after the marriage on their own, and if it cannot reasonably be expected that this gap can be closed in the short term through increased employment.
The issue is less about comfort and more about a realistic assessment of the person’s life situation. Factors such as education, health, employability, age, caregiving responsibilities, and the financial capacity of the other spouse all play a central role. In Switzerland, alimony is primarily an economic and practical question, not a moral judgment.
The Key Topic of “Length of Marriage”: Why 5 Years Matter in Practice
A particularly important practical factor is the duration of the marriage. This is not because there is a fixed legal threshold, but because the length of the marriage is often an indication of whether the marriage has had a lasting impact on one spouse’s life and economic position.
In practice, the following reference points are often used:
Under 5 years, the marriage is often considered rather “short.” This does not mean that an alimony claim is excluded, but it is usually harder to argue that substantial marriage-related disadvantages arose within a short period.
From around 5 years, courts look more closely at whether and how the marriage influenced life planning, for example through giving up employment, role allocation, or location and career decisions made for the benefit of the family.
From around 10 years, courts are more likely to assume a stronger lasting impact on life, especially if employment was reduced or given up during the marriage.
Ultimately, it always depends on the concrete life situation. A five-year marriage can have had a very strong impact, for example where there are small children and a complete interruption of employment, while a ten-year marriage without children and without professional restrictions may under some circumstances justify less need for alimony.
Infidelity as a Ground for Divorce: Does It Affect Alimony?
Many people intuitively expect infidelity to matter. Under Swiss alimony law, yet, this is generally not the case. The system is largely independent of fault. This means: whether someone was unfaithful or not will generally neither automatically lead to more alimony for the affected spouse nor automatically reduce alimony for the unfaithful party.
Instead, the alimony question is assessed independently of the ground for divorce: What economic consequences has the marriage left behind? What earning possibilities exist? What is reasonable? And what is financially possible at all?
It is also important to note that an alimony claim presupposes that the other spouse has the financial capacity to pay. If, after deducting child-related costs, housing costs, and minimum living expenses, no financial room remains, even an otherwise justified maintenance need cannot be fully covered.
How Long Does Post-Divorce Alimony Last?
The duration of post-divorce alimony is one of the most common points of dispute, and at the same time one that cannot be answered in general terms. Courts usually look at how long it will take until a person can again become financially self-sufficient, or whether this is only possible to a limited extent for objective reasons.
Typical constellations include:
Transitional alimony is often granted if a realistic re-entry into the labor market is expected, for example to allow time for job applications, further education, increasing working hours, or arranging a new childcare solution.
Longer-term alimony may be considered if self-sufficiency is permanently or significantly limited, for example due to long employment gaps, health limitations, age, or intensive caregiving obligations.
No alimony or only short-term alimony is more likely if the marriage was of short duration and no substantial marriage-related disadvantages arose.
In many cases, alimony payments are also limited in time or adjusted step by step, for example with an increasing expectation to work over time. The aim is often to allow a fair transition period without losing sight of economic independence.
A Little Comparison with Thai Law
In Thailand, the grounds for divorce traditionally play a much greater role in court proceedings than they do in Switzerland. Infidelity can be more legally relevant there, because the system is more strongly linked to fault. In Switzerland, by contrast, post-divorce alimony clearly focuses on economic and marriage-related factors, regardless of who “caused” the separation.
Conclusion
If you want to understand post-divorce alimony in Switzerland, one guiding question is especially helpful: not “who is to blame,” but rather “who can realistically live on what after the marriage, and from when the person is independent again?” Infidelity is often the emotional trigger of a divorce, but from the perspective of alimony law it is usually not decisive. What matters are the length of the marriage, the division of roles, caregiving responsibilities, earning capacity, and the financial possibilities of both parties.
