Is it always possible though.
for example, my dc do a lot of hobbies. My dad pays for a lot- the trips away, fees, equipment etc.
so a) should he also pay for step gc hobbies. If not, why not?
b) the stepdc have 4 grandparents who could afford to pay. Should my dad still pay in the name of equality?
c) stepdc mum actively discourages hobbies. Doesn’t want to take them, or spend money on it. Her choice. There are a couple of times the step dc have expressed an interest, dh has arranged and paid, for her to refuse to take them, and refuse to allow dh to take them. Once music lessons were arranged by mum in school as dc wanted to do it. Dh paid, only for her to change her mind and just keep the money.
how does a step grandparent pay for things they aren’t allowed to have?
as usual it’s the “even isn’t always fair” issue. Why should my dad write his stepdc into his will, which would mean effectively the step dc will inherit from 4 grandparents of their own, plus my dad. Whereas my child will only inherit from 3, so my child will lose 2/3 of their inheritance.
