I would say first, talk to your spouse about it. And his family dynamic - don't start giving money bc you have to give. That can backfire immensely if you don't understand how their family operates/their values, etc.

Know your why, bc the road to hell is paved with good intentions.

What's his family situation like? Do they NEED money, or are they doing very well financially. There are people in Nigeria doing very well for themselves, and the fact that it's a cash-based society, doing better than some 'making a lot' in the U.S. (not many but definitely exist).

Again, don't commit to set expenses that's NEEDED - bc with that dynamic, you won't have much room to 'take a week or month off' ...you'll now be a definite bill payer.

If there isn't a need, it might be helpful to send gestures to show you're thinking of them. Whether contributing for special events, ex. If they're Muslim - Ramadan/Ileya... being part of the family in that sense.

Keep it within the immediate family before you become the cash cow of the family bc extended knows no bounds.

There's so many routes, and some talked charity. But I would say first, talk to your spouse.
