Plaintiff brought this action for damages for injuries he allegedly received in two automobile accidents involving defendants. After plaintiff rejected the mediation award, defendants brought motions for security for costs. The trial court granted the motions and ordered plaintiff to post a bond in the amount of $10,000. When bond was not posted in a timely manner, the trial court dismissed plaintiffs complaint. Plaintiff appeals as of right. We reverse.
The trial court abused its discretion in imposing a $10,000 surety bond requirement on plaintiff pursuant to MCR 2.109, because under the circumstances such a requirement was unreasonable. There was no error in the circuit court’s finding that defendants demonstrated substantial reasons for the imposition of security. Farleigh v Amalgamated Transit Union, Local 1251, 199 Mich App 631; 502 NW2d 371 (1993); Wells v Fruehauf Corp, 170 Mich App 326; 428 NW2d 1 (1988); Flanagan v General Motors Corp, 95 Mich App 677; 291 NW2d 166 (1980); Gaffier v St Johns Hosp, 68 Mich App 474; 243 NW2d 20 (1976). Nor were defendants’ motions untimely merely because they were filed soon after mediation. There were adequate explanations in that defendants were facing further discovery and trial requirements and they had very recently discovered evidence that seriously damaged plaintiffs claims. Hall v Harmony Hills *254Recreation, Inc, 186 Mich App 265; 463 NW2d 254 (1990).
However, the trial court erred in concluding that plaintiff failed to demonstrate that he was financially unable to post a bond. We review the trial court’s imposition of security under the abuse of discretion standard. Farleigh, supra. The pertinent portions of MCR 2.109 provide:
(A) Motion. On motion of a party against whom a claim has been asserted in a civil action, if it appears reasonable and proper, the court may order the opposing party to file with the court clerk a bond with surety as required by the court in an amount sufficient to cover all costs and other recoverable expenses that may be awarded by the trial court, or, if the claiming party appeals, by the trial and appellate courts. The court shall determine the amount in its discretion. . . .
(C) Exceptions. Subrule (A) does not apply in the following circumstances:
(1) The court may allow a party to proceed without furnishing security for costs if the party’s pleading states a legitimate claim and the party shows by affidavit that he or she is financially unable to furnish a security bond.
Here, the trial court believed that a bond was appropriate absent plaintiff’s poverty, but it then failed to assess plaintiff’s financial ability to post the bond. Plaintiff’s cause of action was for personal injuries, the severity of which was closely contested. Plaintiff did demonstrate, at a minimum, a fractured ankle, and his mediation evaluation was in the amount of $10,500. The court, however, thought that plaintiff was exaggerating his claims and symptomatology, and that he would be unable to support certain physical claims, including sexual dysfunction, impotency, bladder *255and bowel dysfunction, and a treatment claim of self-catheterization. In so doing, the court came perilously close to assessing credibility.
We find abuse of discretion in the court’s refusal to assess plaintiff’s financial ability to furnish the security bond, which the court effectively set within a whisper of the mediation evaluation. Plaintiff filed an affidavit of indigence indicating that his sole income was $1,200 a month in the form of social security disability benefits. The court found the affidavit insufficient but did not say why. The court stated:
Yes. I would have to say there was no affidavit at the time of the original motion regarding the— whether the Defendant — or the Plaintiff was indigent or not. And subsequently this affidavit was filed today, but it does appear to be insufficient. And therefore I will sign — I will refuse to consider this, although it does show that he does make twelve hundred dollars a week — or twelve hundred dollars a month. That may be — let’s check that.
Twelve hundred dollars per month from Social Security and some kind of disability. That would not — would not seem to preclude him from posting this bond.
The court also commented that plaintiff’s wife appeared to have a good job. However, plaintiff’s wife was not a party to this lawsuit. At the conclusion of the hearing, the trial court entered its order requiring plaintiff to file a surety bond in the amount of $10,000 within twelve days. On the thirteenth day, November 17, 1992, the trial court entered its order of dismissal with prejudice. We are left with a definite and firm conviction that the court erred and we therefore reverse the order requiring a surety bond in the amount of $10,000 and reinstate plaintiff’s claim.
*256Reversed.
