Is it permissible to sell a daughter’s gold without her knowledge to buy an uncertified plot of land for her upon her reaching legal age, and is it better to relinquish ownership of land in exchange for debts or to draw up a sale and purchase contract?

A daughter's money, whether from inheritance or a gift, must be made available to her, and no one has the right to dispose of it after she reaches maturity and sound judgment, except with her permission. This is based on the Almighty's saying: "And test the orphans until they reach the age of marriage; then if you perceive in them sound judgment, release to them their property." She has an independent financial standing and the right to dispose of her money as long as she is of sound judgment. If her sound judgment is not apparent, then only what she needs should be given to her from her money, based on the Almighty's saying: "And do not give the incompetent [sufahaa’] your property."

If the daughter is not of sound judgment, her money should not be handed over to her, and only the guardian or trustee should manage it. If you are not a trustee, the matter must be brought before the Sharia (definition) court to appoint a guardian. However, if you are a trustee, it is permissible to manage her money in a way that serves her best interest, such as converting it into real estate, provided it does not harm her.

As for a trustee purchasing real estate for his daughter from his own money, this is a matter of scholarly disagreement among jurists; some have prohibited it, while others have permitted it if it serves the daughter's interest or if the trustee adds to the price. It is advisable to consult a Sharia judge or trusted scholars on this matter.
