You know the not put everything through the books type of people? How do you calculate child maintenance from them?

My sisters ex was giving her £300pm maintenance but because she's booked a holiday he's told her he's only going to give her £200pm and use the extra £100 for clothes She now wants to get CSA involved

£100 for clothes - for him or for the kids?

For the kids. For when they are at his house.

Clothes for him or the kids?

It would depend on how much he declares through the books which is where this can get a bit fishy with self employed people.  generally it is worked out as 5% per child by the CSA BUT remember that someone who is self employed could go off-radar if it suited them

I don't see how you can get a fair calc if they're not declaring their earnings. If they're screwing their tax return then the CSA (rather, your sister) will be screwed too.

For the kids at his house. £200 per month works out to £3.33 per girl per day. He doesn't put half a much as he should through the books....

He is a tw@t of the highest order but what is new.  Even if he paid £100 towards the kids clothes a month he would probably buy them a designer top each for £100 rather than clothes they need.  This is all becuase he doesn't want her but he doesn't want her getting on with life without him - makes my blood boil

I have just worked it out on a guestimate of his earnings (from what I know!) and it is stating £80 per week minimum which is £346.67 a month

He declares £17k - 19k Neen!

Interesting, in that case she needs to try and settle outside of CSA I think as that would work out £58 a week which is £251.34

Yeah it'll be calculated on what he declares

She has mentioned previously she'd rather just do it through them so he can't get out of paying if if she is worse off but I've said that's no guarantee he can still not pay. Best thing for her is to see a solicitor and get some kind of agreement drawn up.

Or grass him up for not declaring...

initial reaction is yes but where does that get her - it just kicks off even more doesn't it.

To be fair I dont agree with self employed not putting stuff through the books, so in my shoes, Id take the moral hugh ground and grass him up. FFS they are his kids, why do 'men' (not all but you know what I mean!) want to take that away from them? DO they share joint custody?

How does she survive financially? DOes she work?

He sounds a twonk. Either get a solicitor on the case (does she get Legal Aid at all - if it still exists even) or tell him he's being reported to CSA and HMRC. See which scenario scares him more.

I've told her time and time again she needs to get a solicitor involved but this is my sister and she just buries her head in the sand. She works five days a week, 9-3
