However, your pension will be tied up in her employer's plan and you will not get any ongoing contributions or bumps as she continues working there.
Essentially, your share is "frozen" at the time of the QDRO and that money is also locked up in that plan (limited to its investment choices and defined benefits). You may want to move that money to an IRA or your employer's plan. If you're in a job that just happens to be part of the same plan (e.g. state plan) you may get benefit from cumulative years contributing to the pension. This is true for many government pensions - you only contribute when your in, but if you leave and come back, the effect is cumulative for the plan.
The QDRO is the court order for the plan administrator to transfer ownership of assets/funds from one taxpayer to another (SSN #).
There may be some liquidation/selling of assets in the plan to convert it to cash since only cash is ever transferred. i.e. you can't transfer shares of stock or mutual fund or bond holdings. Some portion will be sold to arrive at the cash needed, and then they will write a check. They will have choices about what you want them to do with the check - fund your new spousal account within the plan, or send it to some other qualified account (IRA, 401K, etc.), or to you, minus the standard withholding/penalty. Be careful with that if they do, since you have to come up with that money yourself to "top off" the deposit into the new account - and you have to wait until you file your taxes to get it back.
