Marsteller Credit & Debt Lawyer, Pennsylvania

A person who makes a legally binding promise to either pay another person's debt or perform another person's duty if that person defaults or fails to perform. The guarantor gives a 'guaranty,' which is an assurance that the debt or other obligation will be fulfilled.

A person who supports and maintains a household, with or without other people. In bankruptcy law, a householder, housekeeper or head of household can claim a homestead exemption and possibly other exemptions relating to the maintenance of the household.

A claim made by someone who allegedly owes money, that the amount should be reduced because the other person owes him money. This is often raised in a counterclaim filed by a defendant in a lawsuit. Banks may try to exercise a setoff by taking money out of a deposit account to satisfy past due payments on a loan or credit card bill. Such an act is illegal under most circumstances.

A formula that uses predefined income and expense categories to determine whether a debtor whose current monthly income is higher than the median family income for his or her state should be allowed to file for Chapter 7 bankruptcy.

Unauthorized use of a protected trademark or service mark, or use of something very similar to a protected mark. The success of a lawsuit to stop the infringement turns on whether the defendant's use causes a likelihood of confusion in the average consumer. If a court determines that the average consumer would be confused, the owner of the original mark can prevent the other's use of the infringing mark and sometimes collect damages.

A payment made by a debtor to a creditor within a defined period prior to filing for bankruptcy -- within three months for arms-length creditors (regular commercial creditors) and within one year for insider creditors (friends, family members, and business associates). Because a preference gives the creditor who received the payment an edge over other creditors in the bankruptcy case, the trustee can recover the preference (the amount of the payment) and distribute it among all of the creditors.

A term that describes a profit-making corporation organized under state law whose shareholders have applied for and received subchapter S corporation status from the Internal Revenue Service. Electing to do business as an S corporation lets shareholders enjoy limited liability status, as would be true of any corporation, but be taxed like a partnership or sole proprietor. That is, instead of being taxed as a separate entity (as would be the case with a regular or C corporation) an S corporation is a pass-through tax entity: income taxes are reported and paid by the shareholders, not the S corporation. To qualify as an S corporation a number of IRS rules must be met, such as a limit of 75 shareholders and citizenship requirements.
