DP and I have a blended family with three dependent DC. Two DC have had a parent die and 1 DC is the biological child of both of us. We both parent all the DC together and have parental responsibility for all three DC.
As a result of their parent dying, two DC get a pension until they are 18 which we save for them in their own bank accounts. They don't know about the money yet (as they are primary school age). They will get quite different amounts of money from each other (due to being different ages when their parent died) but the amount will eventually be around £20000-£25000.
Should we save money for the other DC to even things up monetarily? Obviously, there is no "fair". It's not fair that 2 DC lost their parent. I'm just interested in outside opinions to check if one option seems better than the others:
We could leave things as they are, or if we add any money to savings make sure we always split it equally in thirds.
We could save some extra money for biological DC, maybe aiming for about £10000 by the time they are 18. We could do this in their own savings account, or just plan to give it to them as an adult, if they seem unlikely to blow it all on heroin/gambling/Pokemon cards. (I'm a bit nervous about the money 2 DC will have free access to at 18. Obviously it will be very useful if they are sensible with it but you're still maturing at 18.)
We could aim for making things as even as possible so DC all get a similar amount, adding about £25000 extra for 1 DC, and £5000 extra for the DC who was older when their parent died.
We could do something different that we haven't thought of yet.
I'm leaning towards option 2 and saving something significant extra but not trying to match what the others will have. Is that reasonable? Most important to me is not causing resentment between siblings but I appreciate that all these options could appear unfair from someone's perspective.
