Tenthlining Software for Legal Professionals

Tenth lining (also written as "tenthlining") refers to numbering lines at every 5th or 10th interval on a legal document. Courts require this so that judges, attorneys, and clerks can quickly cite specific lines during proceedings. Tenthliner automates this process so you don't have to do it manually.

Upload your PDF and Tenthliner gets to work immediately. By default, line numbers are added at every 10th line with page indexing enabled, the most common court requirement. If your filing has different needs, you can adjust the interval, toggle page numbering, or enable additional formatting options in the settings before processing. You can also upload multiple documents at once to handle an entire bundle in one go.

Tenthliner accepts PDF files, including native digital PDFs, scanned documents, and handwritten documents. Each file can be up to 50MB.

Yes. Tenthliner supports batch uploads so you can process multiple documents in a single session, saving you time when preparing large court filings or bundles.

No. Once you upload your document, processing happens on our servers in the background. You can close the tab, shut down your device, or switch to a different device entirely. Log back into your account from anywhere and your processed document will be waiting in your history, ready to download, for up to one hour after processing completes.

Your original uploaded document is deleted from our servers immediately after processing. The processed output is kept for one hour so you can re-download if needed, then permanently deleted. Legal documents are sensitive and we treat them that way.

Yes. Every credit purchase comes with an eTIMS-compliant invoice, making it easy to account for the expense whether you are a solo practitioner or part of a larger firm.

Tenthliner uses a simple credit system where 1 credit processes 1 page. Credits never expire. Pricing is volume-based, so the more credits you purchase at once, the lower your cost per page. Every new account also starts with 50 free credits, no credit card required.
