We are splitting up next year. I have been married for 20 years. I have been inputting to a private pension for 38 years. Is my wife entitled to a share of my pension covering the full 38 years or just 20 years.
If you and your wife intend to make an agreement as a Consent Order the agreement can be very flexible, pensions can`t be considered alone, its the big picture that counts, respective income assets and pensions.
Yours is a long marriage so all assets are marital including your full pension, not just the value of while you were together.
How you approach matters will depend on your needs and your objectives.
For example, how will you both rehouse yourselves. If this is not your primary goal then you can look to offset some of your pension against your share of the matrimonial home (or other non pension assets).
Unless you do look at offsetting the pension I cannot see why the division of the house would not be 50:50.
The only thing you have not mentioned is maintenance. If there is a differential between your earnings and earnings capacity this may be part of a settlement.
If this is the cashe you may wish to capitalise these payments to ensure a Clean Break in which case the split may not be 50:50.
