I am a family law attorney (along with wills and trusts with decades of experience.
My daughter all have college degrees, and professional degrees and are licensed professionals.
That said, they did not leave with college debt. I would much rather pay to make sure they have earnings capability than to support a son in law in Kollel.
WHY?????
Having handled far too many divorces over the years for Jews and non-Jews. The young lady will never lose her education and earning ability if the marriage ends in divorce, but the investment in a son in-law learning in kollel is thrown away money after the divorce.
Let the man’s parents pay for it if they want to, but it is not the woman’s parents’ responsibility.
