Polygamy changes inheritance most sharply when there is no will, because Uganda's intestacy formula was not designed around multiple households. Under the Succession Act as amended in 2022, children share 75 percent of the estate equally regardless of which mother raised them, and the surviving spouse's 20 percent is not multiplied where there is more than one wife. It is shared between them. A written will, made while the father is alive, is the main tool that replaces that generic formula with the family's actual arrangements.
This is said with respect, because the subject rarely receives it. A large share of Ugandan estates involve children of different mothers, through polygamous marriage entered openly and honorably, through remarriage after loss or divorce, or through children acknowledged along the way. However the family came to be shaped this way, it is the family, and the children did not choose their arrival order or their mothers.
Sit with how the formula lands on a real compound. Two widows share 20 percent between them, each of whom spent decades building a separate household. Seven children across three mothers share 75 percent equally, regardless of whose mother's sweat built which asset. The Act also protects the residential home for the surviving spouse and children, which raises its own question in a polygamous estate: which house, and whose occupancy? Administrators must be appointed through a court process that any aggrieved branch can contest, and often does, for years, while school fees stop and rentals decay.
The common misunderstanding is that these families are doomed to fight. The corpus is precise about this: the blended and polygamous estate is not doomed to war, but it defaults to war, and peace must be engineered while the father is alive. The structural reason is that children of different mothers grew up in different houses, at different tables, so the branch rivalry other families meet in the third generation arrives here at the first funeral. The engineering is known and mostly paperwork plus courage: a written will drafted with a lawyer, because a will that simply erases a wife or child invites the court back in; a guardian named per minor child, with funding attached; a plain conversation with each household about what the plan provides for their branch, so no expectation is corrected for the first time by a lawyer reading aloud; separate, documented provision per branch, in title and in named beneficiaries, with the reasoning in a letter; one family council where every branch sits and the branches are deliberately mixed; and burial wishes in writing.
Done well, the result is children of different mothers who meet at their father's funeral as co-heirs who already know each other, whose portions were explained by his own mouth. They will still cry. They will not go to war.
One action: if this is your family's shape, book the lawyer's appointment to write or rewrite the will before the end of this month, and choose which household gets the first expectation-setting conversation. If cost is the barrier, FIDA Uganda and the Uganda Law Society's Legal Aid Project help ordinary families with wills and succession.
