in Fond du Lac, Wisconsin, toward appellee’s railroad crossing. At that point, the single track of appellee Railroad intersected 9th Street at approximately right angles. A northbound train of appellee collided with the right side of the automobile, shoved it northward and to the west where it came to rest facing north in a ditch north of 9th Street. Violet Bosin and her children, Sandra and Robert Bosin, passengers in the car, sustained injuries.
The crossing signals were located at the northeast and southwest approaches to the street and track intersection. They consisted of a post, mounted on which were a cabinet, two flasher lights, a movable octagonal stop sign surmounted by crossed arms bearing the words “Railroad” and “Crossing”.
On the evening preceding the accident, a Fond du Lac policeman, traveling east on 9th Street, observed the crossing signal in stop position, and that the flasher lights were not operating. He testified that he observed the large yellow stop sign and stopped his car before proceeding across the track. Efforts to reach a railroad signal maintainer proved fruitless and the flasher lights continued to be out of order on the following morning.
Liability of appellant City was predicated on a large tree located in that quadrant of the intersection directly related to the accident. The center of the trunk of this tree was 45% feet west of the center line of the railroad track, between the curb line and the sidewalk along the south side of 9th Street. The branches spread out a distance of 41 feet and at the trunk were six feet above ground level. In response to interrogatories, appellant admitted that this tree was within the jurisdiction of the City of Fond du Lac, within the street right-of-way and that the date of trimming of said tree by the City, if any, prior to the date of the accident, was unknown,
Appellant City’s first contention is based on Section 62.25(1) (a), Wis.Stats. (1955) which states: “No action shall be maintained against a city upon a claim of any unyi the claimant shall first preSent his claim to the council and it is disallowed in whole or in part. * ” jt was stipulated that no official notice or claim was filed with the City of Fond du Lac or any official of the City.
The question presented is whether noncompliance with the above statute bars a claim for contribution in a third-party proceeding. We agree with the trial court that non-compliance with the statute is not a bar under the circumstances of this ease.
The right of contribution between joint tortfeasors arises at the time of the concurring negligent acts. Until one of the joint tortfeasors pays more than his proportionate share of the underlying claim, the right remains contingent, subordinate and inchoate. When a tortfeasor pays more than his proportionate share, the right ripens into a cause of action. Ainsworth v. Berg, 253 Wis. 438, 34 N.W.2d 790, 35 N.W.2d 911 (1948); Western Casualty & S. Co. v. Milwaukee G. C. Co., 213 Wis. 302, 251 N.W. 491 (1933); De Brue v. Frank, 213 Wis. 280, 251 N.W. 494 (1933).
Ainsworth v. Berg, supra, further illustrates the nature of the right of contribution as it exists in Wisconsin. In that case, Ainsworth and his employer sued Berg and his insurance carrier. Defendants sought to implead, as joint tortfeasors, persons who had not been given timely notice of injury by plaintiff, as required by Section 330.19(5), Wis.Stats. (1947).2 In holding that the right of contribution is not impaired by the statutory duty imposed upon injured persons,
