Costilla Wills & Probate Lawyer, New Mexico

A defendant's court papers that seek to reverse the thrust of the lawsuit by claiming that it was the plaintiff -- not the defendant -- who committed legal wrongs, and that as a result it is the defendant who is entitled to money damages or other relief. Usually filed as part of the defendant's answer -- which also denies plaintiff's claims -- a counterclaim is commonly but not always based on the same events that form the basis of the plaintiff's complaint. For example, a defendant in an auto accident lawsuit might file a counterclaim alleging that it was really the plaintiff who caused the accident. In some states, the counterclaim has been replaced by a similar legal pleading called a cross-complaint. In other states and in federal court, where counterclaims are still used, a defendant must file any counterclaim that stems from the same events covered by the plaintiff's complaint or forever lose the right to do so. In still other states where counterclaims are used, they are not mandatory, meaning a defendant is free to raise a claim that it was really the plaintiff who was at fault either in a counterclaim or later as part of a separate lawsuit.

A surviving spouse's right to receive a set portion of the deceased spouse's estate -- usually one-third to one-half. Dower (not to be confused with a 'dowry') refers to the portion to which a surviving wife is entitled, while curtesy refers to what a man may claim. Until recently, these amounts differed in a number of states. However, because discrimination on the basis of sex is now illegal in most cases, most states have abolished dower and curtesy and generally provide the same benefits regardless of sex -- and this amount is often known simply as the statutory share. Under certain circumstances, a living spouse may not be able to sell or convey property that is subject to the other spouse's dower and curtesy or statutory share rights.

An ownership interest in the minerals contained in a particular parcel of land, with or without ownership of the surface of the land. The owner of mineral rights is usually entitled to either take the minerals from the land himself or receive a royalty from the party that actually extracts the minerals.

A trust that allows couples to reduce or avoid estate taxes. Each spouse puts his or her property in an AB trust. When the first spouse dies, his or her half of the property goes to the beneficiaries named in the trust -- commonly, the grown children of the couple -- with the crucial condition that the surviving spouse has the right to use the property for life and is entitled to any income it generates. The surviving spouse may even be allowed to spend principal in certain circumstances. When the surviving spouse dies, the property passes to the trust beneficiaries. It is not considered part of the second spouse's estate for estate tax purposes. Using this kind of trust keeps the second spouse's taxable estate half the size it would be if the property were left directly to the spouse. This type of trust is also known as a bypass or credit shelter trust.

A bypass trust funded with an amount no larger than the personal federal estate tax exemption in the year of death. If the trust grantor leaves property worth more than that amount, it usually goes to the surviving spouse. The trust property passes free from estate tax because of the personal exemption, and the rest is shielded from tax under the surviving spouse's marital deduction.

A will that is created in a way that allows a probate court to easily accept it as the true will of the person who has died. In most states, a will is self-proving when two witnesses sign under penalty of perjury that they observed the willmaker sign it and that he told them it was his will. If no one contests the validity of the will, the probate court will accept the will without hearing the testimony of the witnesses or other evidence. To make a self-proving will in other states, the willmaker and one or more witnesses must sign an affidavit (sworn statement) before a notary public certifying that the will is genuine and that all willmaking formalities have been observed.

Someone appointed by a probate court to oversee probate proceedings when a person dies without a will or heirs, and his or her property is expected to pass to the state. Some states have public administrators who are responsible for temporarily preserving the assets of an estate if there are disputes about specific provisions in the will or about who will be appointed the regular administrator.

A trust created for a beneficiary the grantor considers irresponsible about money. The trustee keeps control of the trust income, doling out money to the beneficiary as needed, and sometimes paying third parties (creditors, for example) on the beneficiary's behalf, bypassing the beneficiary completely. Spendthrift trusts typically contain a provision prohibiting creditors from seizing the trust fund to satisfy the beneficiary's debts. These trusts are legal in most states, even though creditors hate them.
