Zimbabwe’s Marriages Act commenced on September 16, 2022, and the High Court has refused to use its civil partnership rules to recast an earlier completed union. The timing matters more than people sometimes assume.
Section 41 now gives qualifying unmarried couples a route into parts of the Matrimonial Causes Act when their relationship dissolves. The recognition of civil partnerships in Zimbabwe therefore carries real financial consequences, but a newer statute does not automatically reach backward and change the legal character of events already finished under the old law.
A 2023 High Court dispute put the problem in unusually clear terms. Nomsa Almero and Johane Sithole had entered a customary law union in 2010, lived as husband and wife, had three children, and acquired property during the relationship. Their union was said to have ended in January 2018, years before the new Act started operating.
The High Court refused the amendment. Its problem was not simply that the relationship had started before 2022. More importantly, the customary union had already ended before the new legislation came into force, so applying section 41 would have changed the legal effect of a completed relationship after the fact.
Zimbabwean law generally starts from a presumption against legislation operating retrospectively unless the wording clearly requires that result. The Marriages Act did not expressly say section 41 should reach back and transform completed pre-Act relationships. In this case, the court was not prepared to make the statute do that work.
This is an easy point to overstate. The judgment did not announce that every relationship beginning before 2022 can never fall within the modern civil partnership framework. It dealt with a union said to have ended in 2018 and an attempt, years later, to use a 2022 statute to change the legal basis of an existing case.
This matters because an old customary union and a civil partnership are not interchangeable labels. Almero’s case involved lobola and a relationship described as an unregistered customary law union. Section 41, by contrast, asks whether unmarried adults lived together as a couple on a genuine domestic basis and then provides particular remedies when that civil partnership dissolves.
The distinction remains important in analysis of women’s rights in unregistered customary marriages because property consequences can change sharply depending on which legal category applies. Calling every pre-2022 informal relationship a civil partnership would skip the formation rules and history that made some of those relationships customary unions in the first place.
Dates therefore need to be pinned down before anyone reaches for section 41. When the relationship began, what legal form the parties intended, whether customary formalities occurred, when the relationship ended, and when proceedings started can all affect which body of law is doing the work.
Those older causes of action work differently from section 41. A claimant may need to prove contribution, a partnership arrangement, enrichment, or another recognized basis for relief instead of relying on the Matrimonial Causes Act machinery imported for modern civil partnerships. The difference is procedural and substantive, not just a change of vocabulary.
Children were treated separately too. The court made clear that custody, maintenance, access, and guardianship did not depend on successfully converting the parents’ old relationship into a civil partnership. Existing child-law rules and the best-interests principle continued to govern those issues.
The practical trap is rewriting history because today’s statute offers a cleaner remedy. A relationship terminated before the Act cannot simply be renamed after the event because the newer category looks more useful in a property fight. Courts still have to apply the law attached to the relationship and transactions when they actually occurred.
For disputes straddling 2022, the dates become part of the legal substance rather than background trivia. A relationship continuing across commencement presents a different factual problem from one conclusively terminated years earlier, while an old customary union may also engage the Act’s transitional provisions instead of section 41. The file needs a timeline before it needs a label.

The court would not turn an old union into a new one
Almero had already brought proceedings in 2018 involving children, maintenance, property, and other relief. After the new Marriages Act arrived, she sought to amend her case so the former relationship could be treated as a civil partnership under section 41.The High Court refused the amendment. Its problem was not simply that the relationship had started before 2022. More importantly, the customary union had already ended before the new legislation came into force, so applying section 41 would have changed the legal effect of a completed relationship after the fact.

Older customary unions did not simply disappear
The Act itself contains transitional rules for customary marriages contracted before commencement. Existing marriages valid under earlier law were not wiped away, and parties to qualifying unregistered customary marriages contracted before the Act were given a route to registration under the new framework.This matters because an old customary union and a civil partnership are not interchangeable labels.

Losing section 41 does not necessarily erase every claim
The High Court did not say a person in an older unregistered customary union must automatically walk away with nothing. Almero’s existing pleadings included arguments based on a tacit universal partnership and unjust enrichment, routes Zimbabwean courts had dealt with before the new civil partnership regime existed.Those older causes of action work differently from section 41.
