If the mother spends on her children instead of the father, can she claim it back from him if he becomes wealthy?

Question:
He says: Honorable Shaykh, may Allah grant you success, the father who refused to provide financial maintenance for his children, and their mother was providing for them, and she intended to claim the money back from the father. Does the debt lapse with the passage of time?

Answer:
Shall I repeat the question? The father who refused to provide financial maintenance for his children, and their mother was providing for them, and she intended to claim the money back from the father. This falls under, yes, it falls under what was previously conveyed to you: if someone spends on a person with the intention of claiming it back, in place of the one who is obligated to provide maintenance for him, he has the right to claim it back.
