Could it be more emotional than financial? As in the whole family should give what they can?
My grandma (who I very much hope has lots of time left to live), doesn’t have much in terms of money and nothing in terms of asset, though I am sure she’s prepared everything to have her death covered (it’s a topic we discuss a lot.) Two of my aunts are rich and could easily cover her funeral if ever needed BUT I would still want to participate, I adore ny
grandma I would be completely devastated if/when she dies.
Her funeral would be my final goodbye to her so anything I could do financially I would want it done, irrelevant of if my aunts can easily cover it and not feel the hit.
So for me it would be emotional, and I don’t know if the rest of the family would expect me and the others to fork in but I wouldn’t be surprised if they did at all, but for as flawed as my family is, that’s just how we would naturally react, irrelevant of our finances I think most of us would want to fork in but then again she is beyond loved and the pillar of our family so paying for her funeral wouldn’t ever became a source of fighting or of “who should pay”.
Not sure about your husband and his family/relationship to his grandmother, I just know that for me and mine it would all be about paying back towards grandma rather than who can easily afford it and most of us would spend our last penny on it if that’s what it would take for her to have the goodbye she deserves.
Different families have different relationships and different priorities though, hence me asking if it’s really so she doesn’t have to pay for her own mother’s funeral or if it’s because she expect her son to naturally want to participate?
