accession

Coming into possession of a right or office; increase; augmentation; addition. The right to all which one's own property produces, whether that property be movable or immovable; and the right to that which is united to it by accession, either naturally or artificially. The right to own things that become a part of something already owned; e.g. riparian owners' right to abandoned river beds and rights of alluvion by accretion and reliction. Manry v. Robison, 122 Tex. 213, 56 S.W.2d 438, 443, 444.

See accretion.

A principle derived from the civil law, by which the owner of property becomes entitled to all which it produces, and to all that is added or united to it, either naturally or artificially, (that is, by the labor or skill of another) even where such addition extends to a change of form or materials; and by which, on the other hand, the possessor of property becomes entitled to it, as against the original owner, where the addition made to it by his skill and labor is of greater value than the property itself, or where the change effected in its form is so great as to render it impossible to restore it to its original shape.

Generally, "accession" signifies acquisition of title to personal property by bestowing labor on it which converts it into an entirely different thing or by incorporation of property into a union with other property. IDS Leasing Corp. v. Leasing Associates, Inc., Tex.Civ. App., 590 S.W.2d 607, 609.

The commencement or inauguration of a sovereign's reign.

International law.

The absolute or conditional acceptance by one or several nations of a treaty already concluded between other sovereignties. It may be of two kinds:

- First, the formal entrance of a third nation into a treaty so that such nation becomes a party to it; and this can only be with the consent of the original parties.

- Second, a nation may accede to a treaty between other nations solely for the purpose of guarantee, in which case, though a party, it is affected by the treaty only as a guarantor.
