3,671. Redeeming Yourself

Hilchos Bikkurim 11:2

Women are not obligated in redeeming firstborn sons; only one who would be obligated to redeem himself would be obligated to redeem his son. If a father violates the law by not redeeming his son, then the son must redeem himself when he reaches the age of majority.

Hilchos Bikkurim 11:3

If a man must redeem both himself and his son, he should redeem himself first and his son after. If he only has enough money to redeem one of them, it should be himself.
