“Non-owned automobile” means an automobile ... not owned by or furnished for the regular use of either the named insured or any relative, other than a temporary substitute automobile.
However, the non-owner’s endorsement attached to the policy in question states that it becomes a part of the policy to which it is attached, that the insurance afforded by the policy for bodily injury liability and property damage liability applies with respect to the use of any automobile by or in behalf of the named insured subject to the following provisions:
• The insurance does not apply
(a) to any automobile owned by the named insured.
The other listed exclusions are not pertinent to this case. We interpret the endorsement according to its plain language. That interpretation compels us to hold that the policy provided bodily injury liability and property damage liability coverage for Booth while he was driving the Chevrolet automobile which was furnished for his regular use. We find that this definition comports with the purpose of the non-owner’s endorsement as is explained in Fire, Casualty and Surety Bulletin, Personal Auto En-1, (January, 1982), an insurance industry publication:
The most usual need for the Extended Nonowned [sic] endorsement, perhaps, is to delete the exclusions of nonowned [sic] auto ‘furnished or available for the regular use’ of the named insured or any family member. If, for an obvious example, the named insured is allowed to drive a work car home on a regular basis and use it for personal use, a regular Personal Auto policy does not provide coverage as to that ear — while it is being used by anyone. Likewise, a car furnished to a family member of the named insured is not covered, except with respect to the named insured’s use of the car. The Extended Nonowned [sic] endorsement deletes both exclusions as they would otherwise apply to the individual named in the endorsement. (Emphasis added).
EFFECT OF THE DECLARATORY JUDGMENT
Childress filed suit against Booth on May 17,1976. Dairyland hired attorney Mark T. Davenport to defend Booth and paid him for his services. Davenport filed an answer for Booth on June 4, 1976. On June 16, 1976, Dairyland filed suit for declaratory judgment that the non-owner’s policy did not provide Booth coverage for the collision with Childress. On January 17, 1977, an agreed judgment was rendered that Dairy-land had no duty to defend Booth and that the non-owner’s policy provided no coverage for Booth respecting the collision with Chil-dress. On July 18, 1978, judgment was rendered for Childress in this suit against Booth.
Dairyland relies upon the doctrines of res judicata and collateral estoppel to support its contention that Childress is bound by the declaratory judgment. Their argument is that Childress’ suit is derivative of Booth’s coverage and therefore they are in privity with Booth, citing
Benson v. Wanda Petroleum Co., 468 S.W.2d 361 (Tex.1971);
Kirby Lumber Co. v. Southern Lumber Co., 145 Tex. 151, 196 S.W.2d 387, 388 (1946);
Cain v. Balcom, 130 Tex. 497, 109 S.W.2d 1044 (1937); and
Davis v. Dairyland County Mutual Insurance Co. of Texas, 582 S.W.2d 591 (Tex.Civ.App.—Dallas 1979, writ ref’d n.r. e.). Our examination of the cases cited by Dairyland reveals that they are all distinguishable from the instant case on their facts.
Kirby Lumber and
Cain v. Balcom involved real estate title disputes. Both cases held that a grantee of a deed to real property is in privity with his grantor. In
Davis v. Dairyland, the plaintiffs were attempting,
as assignees of the insured to recover from the insuror. The court of civil appeals carefully limited its decision to the facts involving an assignee of the insured.
