Parents who "sell" property to a favoured child without real consideration — typically to favour them over the others — fall under "muris muvazaası".
Indicia
No actual price paid, the testator's continued use of the asset, family relationship with the "buyer", unusually low price. All considered.
Legal effect
The sham contract is void. The asset returns to the estate. Disadvantaged heirs can claim their reserved or legal share.
Time limit
Unlike the reduction suit, this suit has NO time limit. It can be brought decades after the death.
Evidence
All forms admissible — witnesses, messages, bank transfers, the testator's post-sale conduct. The more objective evidence, the higher the chances.
Difference from reduction
Reduction: valid dispositions reduced for reserved heirs. Muris muvazaası: void sham dispositions, void from the start.
