Griffdog, you cannot legally sell your pension.  Nor can anyone legally buy it.  That is because pensions are not your "property." 

Know that pension plans are not legally allowed to disburse from their "principal accounts."  They must invest those funds providently and the SEC has long had rules in place that forbid the practice.  You therefore get the interest, as allotted by your pension fund, in scheduled periodic amounts.

The exception is your individual retirement plan: Keoughs, IRA's, and other pension plans, allow you to withdraw funds in emergencies -- all stipulated in your contracts.  If you DO make an early withdrawal, you will lose at least 1/5 of the principal and ALL the unearned interest.  That can be disastrous for a pensioner.

In short, it is not a good idea to compromise your future now that your earnings potential is severely limited.
