Hi I am paying for a house in installments. I want...

According to Qatari law, in the event that a house or property is purchased by installments, an initial sale contract is drawn up and this contract includes the price of the sale, the down payment, the installments, and the expiry date thus at the end of the last installment, a final sale contract can be issued similar to the previous contract and the ownership is registered in your name. We recommend that you have payment receipts when there is any dispute over a premium that has been paid as a price meeting for the purposes of registration for you.

Thanks for clarification, regarding selling the property or assigning it, it is possible to remain in the name of the owner after it is worth it, and if it is by way of installments, but for the guarantee of rights, a power of attorney can be made for any friend residing in the state who is responsible for managing and caring for and benefiting from what makes profit
So the best way is to make a power of attorney for anyone who is trusted in your dealings. There are no other ways if you want to keep ownership in the name of the seller.
