Hi there Mark:-

I'm confused by this:-

"I have had our property re-valued as the original valuation was done in March and to my shock I have been told by two estate agents the property has risen by approximately £60,000.

This will cause some issues as I had agreed on a financial settlement PRIOR to this new valuation. I do not want to be out of pocket financially because I need to re-start my life and make a comfortable for me and the children"

What are your long term plans in term of the house?

To sell it and split the difference?
Or for one of you to stay put?
If the latter, if you stay put - you buy her out and vice versa...

Mark you're getting some great great input here but don't overlook the fact that the laws and processes in the UK are very different to the US...

Make sure that your actions and decisions are firmly grounded in UK terms...

For maintenance for children the CSA website has an easy calculator to use and this site http://www.wikivorce.com/divorce/ also has lots of useful stuff on it...

Like I say, IMO be cautious about some of the advice cos although it might work well in the US, and by saying this my intention is not to, in any way discredit the advice given, merely to caution you as this sitch is being played out in the UK, and according to UK rules and practice - and there are differences between how the US and the UK see / deal with things...

Best - GFI
