To answer the original questions..Is your wife entitled to a share of your pension..? Your marriage is not a long one .If you had been married say 12 years or more the chances are it would be considered a long marriage and in those circumstances your wife would be entitled to 50% of your pension or even more. Your wife is probably considerably younger than you and a woman so she is likely to live longer .Therefore the pension provider will argue that to give her a reasonable income she needs 50 to 60 % share of your pension pot. However you have been married 6 years and you can argue that she has not really given up much in the way of earning capacity in the marriage to you..ie..she can still work long enough to build up her own pension..
Your other concern..if she has her name as the joint owner of the house does she get 50% of its value..Possibly..There are no hard and fast rules in a financial settlement after divorce unless you live in Scotland..Most things are by negotiation..and in the end it comes down to what is fair and reasonable and the Court has the final decision..
