Meghan came into the relationship with apparently circa £5m to her name. She was given a free house by her in laws in one of the most desirable neighbourhoods in London. Any self respecting feminist would be prepared to pay her bit to the tune of, what, a couple of grand at most out of a huge fortune, as a contribution to the couple's new home.
Harry received £10m at age 30 (2014, before he met Meghan) from Diana's estate. At some point, he received the bulk of the Queen Mother's £14m estate (it was not shared equally with William, he received the majority).
Harry confirmed in the Oprah interview that he has his mum's money. There's no suggestion it is or was withheld from him.
If Nott Cott was in a state, it was Harry who had been living there and put it in a state. I believe interior designer Kelly Hoppen had refurbished it for the previous occupants, Kate and William, so it can't have been that bad, even if it was not to the taste of subsequent occupants. Harry had the means to make it presentable before Meghan moved in.
I don't know who paid for Meghan's wedding dress. There are conflicting reports. However, Kate's parents paid for hers, so perhaps the outfits of those marrying in don't come out of the royal purse as a rule. I don't see what the problem is with a wealthy feminist paying for her own wedding dress.
Author of Harry, Life, Loss and Love, Katie Nicholl, said: “My sources tell me that Meghan wants to make a contribution to the wedding. She’s a feminist and a wealthy and independent woman and the fact is that pretty much all of the wedding cost are being picked up by the royal family.”
