My ds will be going to uni in September and I have another dc likey to go in 2027 as well. I'm divorced and their father doesn't contribute financially, though he has made noises about doing so once they're at uni but I'll believe it when I see it. CMS involved but he's a low earner with wealthy parents/ inheritance.
Each child has a ctf worth around £10k which they expect to have to spend while at uni. My earnings mean they will be able to borrow the minimum amount but it's only in the last few years I've earned at this level. I had to buy ex out of the house, was left with some marital debt and have had to be the sole provider for the dc throughout their lives- ex was sahp. House has also needed some work doing. As a result my savings are minimal though I do have a £20k inheritance which has been in an isa and will mature in 12 months.
Ds1 and I have always had a very open relationship and he is a bit 'old beyond his years.' When we've discussed uni he has been concerned about finances and I've told him about the £20k and phrased it as half each for him and his sibling.
However, now I think I might well be able to meet a fair amount of his monthly costs from my salary and may not need to use all of the 20k/his share of it. I do have to pay a further 10k to ex when youngest child turns 21 so if I could have some left for that it would be great. However, I'm worried ds will see this as unfair and will be expecting the full £10k as that's how I've previously explained it. Does it sound unreasonable not to do it that way and just give him what he needs as and when?
