it'a not a case of as much as you like - it's more a case of what you can negotiate with the other equity partners as your terms and conditions. I'm asking on behalf of a friend who's just become an equity partner and she needs to negotiate this as part of her terms - she's just not sure what would be reasonable - she's the only female equity partner of child-bearing age that they've had for about 10 years! So she doesn't know where to start really. If she takes the piss the other equity partners aren't going to be happy.
But surely if she's equity she only takes drawings at the end of the year when profits are shared out. If she's contributed no profits then surely she gets nothing. It's like being self employed to a certain extent. I know a barrister who's got nothing for the year she's been off apart from SMP.
If she plays it right she could get a certain amount off the firm; I guess she'll just have to bargain with them to a certain extent.
