Okla. Stat. tit. 42, § 42-17: Order of resort for payment of prior liens

Where one has a lien upon several things, and other persons have

subordinate liens upon or interests in, some but not all of the same

things, the person having the prior lien, if he can do so without

the risk of loss to himself, or injustice to other persons, must

resort to the property in the following order, on the demand of any

party interested:

1. To the things upon which he has an exclusive lien.

2. To the things which are subject to the fewest subordinate

liens.

3. In like manner inversely to the number of subordinate liens

upon the same thing; and,

4. When several things are within one of the foregoing classes,

and subject to the same number of liens, resort must be had,-

(a) To the things which have not been transferred since the

prior lien was created.

(b) To the things which have been so transferred without a

valuable consideration; and,

(c) To the things which have been so transferred for a valuable

consideration.
