I may be completely wrong but I wonder if they are playing down the fact of

having the money as again a plot point to boost

self esteem that he has been able to make the big gesture of organising a deposit for their family home - OK

isn't mentioned by name as being part of the house purchase but they are a couple and it is a joint venture. I think that when

was talking the other day and saying that we had cheques and letters etc to organise he was talking more about himself and

because I wouldn't have thought Liv would be able to sign legal documents like that at her young age. I'm sure that it will come out soon enough that

will be contributing in equal amounts to the new home.
I find it quite funny that in some places online they are talking about

going into business with

to earn the money - I wouldn't call what he's doing going in to business I would just call that a consultancy fee for his business knowledge.
Sorry for the long ramble and I'll admit I'm probably way off the mark.
