In Scotland only the part of a pension built up during the marriage or civil partnership, up to the relevant date, is matrimonial property. That is shared equally unless special circumstances justify otherwise. The relevant date is the earlier of the day you stopped living together or the day the divorce summons was served.
In England and Wales the court considers the whole pension along with everything else either of you owns, whenever it was built up, and has a wide discretion over the split. The Scottish rule draws a line at the marriage, so a pension built mostly before it is largely left out.
In Scotland the pension you built before the wedding stays yours. Only the years of the marriage are shared.
No. Only the part referable to the marriage, before the relevant date, is matrimonial property.
The relevant date is the earlier of separation and service of the summons, so pension built up after you separated does not count.
No. In Scotland a pension can be shared under a legally binding agreement between you.
Knowing what the shared part is worth is where the negotiation starts.
