The right to sell a house property typically lies with the: 1. _Property Owner_: The person who holds the title to the property has the primary right to sell it. 2. _Co-owners_: If the property is owned by multiple individuals (co-owners), they may all need to agree to sell the property, unless they have specified otherwise in a co-ownership agreement. 3. _Power of Attorney Holder_: If the property owner has granted someone a Power of Attorney (POA), the POA holder may have the authority to sell the property on behalf of the owner. 4. _Executor of the Estate_: If the property owner has passed away, the executor of their estate may have the right to sell the property as part of the estate settlement process. 5. _Court-appointed Administrator_: In cases where the property owner is incapacitated or deceased, a court-appointed administrator may have the authority to sell the property. 6. _Mortgagee_: If the property is mortgaged, the mortgagee (lender) may have the right to sell the property if the borrower defaults on the loan. Please note that local laws and regulations may vary, and specific circumstances can affect who has the right to sell a house property. Consulting with a legal expert or real estate professional can provide clarity in specific situations.
