I have two adult DDs, one from my first marriage, one from my second. Ten year age difference.
When I got divorced I drew up a will to leave everything (which was bugger all) to my dd1, who was 8 at the time. When I remarried a few years later, obviously my will was no longer valid. I had received £20k from the divorce settlement and my ex kept the house where he still lives. I didn't get any maintenance as I didn't want to be financially dependent on him. The money I got was half the equity in the house we had bought jointly.
My DH had very little money when we married, so my £20k paid for the deposit on a house, which we now own outright. We have been married 26 years. We share all our money equally. We drew up mirror wills a few years ago, and have left everything to each other, then when the last of us dies the estate to be split equally between our two DDs ( obviously one is DHs step DD). Lately, I've been thinking about this. Dd1s father is quite well off and she is his only child. He's also 10 years older than me so may well die sooner than me! She will get everything, possibly up to £1m before IHT. She's already quite well off as her DH inherited quite a bit of money when they got married, and his parents are very well off so they will benefit greatly when they pass away.
My dilemma is this: should we still split our money between the two DDs equally, or should dd2 get a greater %? (FWIW dd2s DH has had a pretty shitty life and his dm has always lived on benefits, whilst his DF, who left when he was a child, barely acknowledges his existence so he won't inherit anything from his family.)
To add, DH was insistent that both girls are treated equally even though dd1 isn't his child.
What would you do?

Do you know for definite if DD1 will inherit that? Are your daughters close to each other? Is your relationship with DD1 good enough for you to discuss your dilema with her?

Tricky. Being equal and being fair may be different. It's lovely that your DH wants both children to inherit equally but it won't necessarily be the fairest way. I'd discuss directly with the children.
I'm in a similar situation, but am the well off child (relatively). My parents divorced, my mum passed away, my sister and I inherited the whole of my mum's estate. It wasn't any where near £1m but allowed me to put down a good deposit on a 3 bed house.

My DH parents are well off, so we're also in line for money there.

My dad remarried, my step mum has one child, a couple of years older than me. Both step mum and step brother have had a tough life, live in a less affluent area of the UK, work hard to make ends meet. If my dad and step mum pass, I'd rather my step brother got a bigger share. He's got one daughter and step mum is his only parent.

Yes, she's the executor of her DFs will and knows the contents. Plus she will receive a substantial inheritance when her 98yr old grandma dies as again it's in her grandmas will.
The girls are very close, always refer to themselves as sisters not half sisters.
@turtletum you're right, being fair may not equate to being equal!
Dd1 earns in excess of £75k whilst dd2 only earns £24k currently, but has only been working for 2 years. Her earnings potential is, however, as high as her sister.
I think I will speak to both the girls about this. Both of them are in no way grabby, and dd1 spoils her little sister lots (she gave her £1k as a wedding present!) so I'm sure she wouldn't want to see her struggle.
