Splitting expenses.

[Thistledew]

We recently had a family event in honour of my DDad. I arranged it but my half-sibling offered to split the cost. I send him a copy of the two invoices for the main costs of the event. He has transferred me half the money for one invoice, so has covered about 1/4 of the cost of the event.

DH and I are comfortably off and would have covered the full cost if there had been no offer to share the cost, but we have to dip into savings a little to do so. I don't know the full details of my sibling's finances but they also appear to be comfortably off. We have a good relationship but are not close.

WWYD? Would you send a message saying "Oi! Where's the other half of your share?" (Or more polite words to that effect), or would you assume that DSibling has contributed all that they feel able to and would be embarrassed to be asked for more?

When you initially discussed it was there any mention of 50/50? Although agreeing to split does imply half and half in my mind, does everyone see it that way?

If you wanted to raise it, could you say something like “did you get the second invoice I sent you?” Therefore implying that they haven’t paid their part of it.
