Peace be upon you. The rights of others are the responsibility of individuals, and one must fulfill them and document them in their will to ensure they are addressed if they are unable to do so during their lifetime. Ask Allah, the Exalted, to grant you success in this matter and strive for it, as this is a commendable action that will not negatively impact your good deeds and record of actions, insha'Allah. May you remain under Allah's care and protection.
