Just a hunch, but it's possible the original poster might be confused by some of these responses. Here's my summary (which may not be complete):
In general, most plans permit a payment only upon limited circumstances: severance of employment, death, disability, etc. (The plan is not a piggy-bank; it's designed for long-term retirement needs, not short-term cash-flow.)
Some plans offer the ability to make a loan to a still-employed participant, generally repaid thru payroll deductions. No plan is required to offer this feature. As stated above, it's trading one debt for another, so may not address your larger problem.
Some plans offer the ability to take an in-service payment if you are still employed beyond a specific age (such as 65). It's not required.
A QDRO ("qualified domestic relations order") might create the right to an "early" payment, but that may not be productive since it is for the purpose of fulfilling a domestic relations order. Most DRO's are related to divorce/separation, and a few are related to child support. Generally, a QDRO will create the ability for someone else to get a payment (ie, spouse/ex-spouse, child's guardian, etc.), rather than a payment to you. It's also possible that the plan itself could limit the timing under a QDRO (for example, not prior to the time the participant could get a benefit); if so, the QDRO is not permitted to alter this plan provision.
If this is a defined benefit plan, the plan may permit a payment only in the form of an annuity (ie, monthly payments), and will not permit any type of lump sum, even with a QDRO.
Declaring bankruptcy will (probably) not create any mechanism to speed up any payment to you.
If this is a defined contribution plan, as stated above, the plan may have a provision that permits hardship distribution. There are tax consequences. Read your summary plan description.
