yes it's clearly not as cut and dried as we thought at first
however, when we met the house was entirely in her name [100%] and I was self-employed for about 5 years - she, effectively, made the mortgage payments and you could say she was 'investing' in the property
by the time we remortgaged to raise some money in 1998, she had a mortgage at, say, £80,000 on a property worth, say, £120,000 and wanted to protect that investment, so she retained 99% stake in the Land Registry amendment
five years later, she stops work but has continued to pay the lions share of the mortgage payment over that 5 year period, so maintaining her status, so to speak, as the bigger stakeholder
it's only over the last 5 years that I was the sole contributor and housing values haven't shot up in the same proportion that they did over the time she was the main contributor
