MO attachment bonds.
Underwritten. Quote on review.

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.

About this bond

What it is and who needs it.

What the attachment bond does

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.

RSMo § 521.050 / § 521.070 (Chapter 521, Attachments)Under RSMo Chapter 521, a plaintiff suing by attachment must file an affidavit and bond in the clerk’s office of the court where the attachment is instituted (RSMo § 521.050), generally in double the amount sworn in the affidavit (RSMo § 521.070), with the court able to fix the amount not exceeding double the amount claimed. Certain suits — by the state or a county, or against non-residents — are exempt. Confirm the amount in the court’s order.

FAQs

Common questions.

If yours isn't here, the bond team can usually answer within the hour.

How much is the Missouri attachment bond? +
This bond is individually underwritten, not flat-rated. The court sets the penal sum — generally double the sum sworn in your affidavit — and a surety specialist underwrites and quotes the premium on that figure, usually within one business day. Send us the court’s order and we’ll return a number.
Why is the bond required? +
Attachment seizes a defendant’s property before judgment, so RSMo Chapter 521 requires the plaintiff to post a bond protecting the defendant. If the attachment is wrongful, the defendant can recover their damages and costs against the bond.
How is the amount set? +
Generally double the amount sworn in your affidavit, with the court able to fix the figure (not exceeding double the amount claimed). Use the amount in the court’s order — send it to us and we’ll size and underwrite the bond on that figure.
How is it underwritten? +
A surety specialist reviews the case and the court-set penal sum, then quotes the premium. On larger penal sums we may ask for financials or collateral before issuing — that is normal for court bonds, which are individually underwritten and quoted on review.
How fast can I get it? +
Attachment runs on a deadline, so we move quickly — a specialist typically returns a quote within one business day, and the executed bond can follow same or next day once you accept.
