Can I use money I have put aside for Tzedakah to pay for my son’s wedding?
My apologies that it took a while to get back to you.
Regarding your question, it depends on the situation. If both the father and the son do not have the money to pay for the wedding, then they are considered needy and they may use maser money to pay for the weeding. It is however preferable to stipulate before the father accepts upon himself to pay for the wedding that he will give money from maser.
If the father has the money to pay for the wedding, but the son doesn’t, then it is controversial if the father is allowed to give his maser money for the wedding, however many poskim say that one may do so. Again it should be stipulated before accepting to pay for the wedding. In addition, it is preferable that the father not use all his maser money to pay for the wedding, but only a portion of it.
