To sue by attachment in Missouri — and seize a defendant’s property to secure a possible judgment — a plaintiff must file a bond with the clerk under RSMo Chapter 521. The court sets the amount, generally double the sum sworn in the affidavit. Because the penal sum is court-set, this bond is individually underwritten: send us your case and a specialist sizes, underwrites and quotes it.
















Attachment runs on a court clock — send us your case, a specialist underwrites and quotes it, and you file with the clerk. Here is the whole thing:
Your details, the case and court, and the penal sum the court set — that is the request. A surety specialist picks it up to underwrite and price it.
A specialist sizes and underwrites the bond and returns your quote, usually within one business day. On larger penal sums we may ask for financials or collateral.
Accept the quote and receive the executed bond, ready to file in the clerk’s office of the court where the attachment is instituted. Wet-ink originals mailed whenever the court insists.
An attachment lets a plaintiff seize a defendant’s property at the start of a suit to secure a possible judgment. Because that is a powerful remedy that can harm a defendant who ultimately wins, RSMo Chapter 521 requires the plaintiff to file an affidavit and a bond in the clerk’s office of the court where the attachment is instituted.
The bond is generally set at double the amount sworn in the affidavit (with the court able to fix the amount, not exceeding double the amount claimed). It protects the defendant: if the attachment turns out to be wrongful, the defendant can recover the damages and costs they suffered against the bond.
A few suits are exempt — for instance, actions by the state or a county, or where the defendant is a non-resident. When a bond is required, the court sets the figure; because the penal sum is court-set, the bond is individually underwritten — a specialist sizes it, underwrites it, and returns a quote, often within one business day, with collateral or financials possible on larger penal sums. If the surety pays a claim, you repay the surety.
These are the actual underwriting fields. Submit once and a surety specialist sizes, underwrites and quotes the bond — usually within one business day.
