Demurrage Time Bar

What it does

A demurrage time bar clause sets a deadline by which the owner must submit its demurrage claim, usually together with named supporting documents such as the statement of facts and the notices, after completion of discharge or some other defined event. If the claim and the required papers are not presented in the agreed form within that window, the clause extinguishes the claim altogether, however valid it would otherwise have been.

These clauses are construed strictly, because their whole purpose is to give the charterer certainty and to force prompt, fully documented presentation. Missing a single required document, or sending the claim a day late, can defeat the entire demurrage entitlement. The bar is procedural rather than about the merits, so a good claim presented late is simply lost rather than merely reduced.

Commercial effect

The time bar shifts a real and sometimes large risk onto the owner, turning demurrage recovery into as much a documentation discipline as a calculation. A substantial claim can be worth nothing if the owner's operators miss the deadline or omit a listed paper, so the clause raises the stakes on the administrative side of every voyage where it appears in the terms.

For the charterer the clause provides valuable certainty: after the deadline passes without a compliant claim, it knows its demurrage exposure is closed and can settle its own accounts and pass-through positions accordingly. The tighter and more document-heavy the bar, the more it favours the charterer, which is why the period and the document list are negotiated with care on both sides.

Owner's perspective

The owner wants the bar period long enough, and the document list short and realistic enough, that its operators can reliably comply at every port in the trade. It resists overly tight windows or demands for documents that may not be available in time, since each requirement is a chance for an otherwise sound claim to fail on a technicality rather than on its actual merits.

Where a strict bar is unavoidable, the owner invests in the internal process to meet it, assembling statements of facts, notices, and pumping logs promptly and presenting them exactly as the clause requires. The owner treats compliance as part of earning the demurrage, knowing the clause will be enforced as written and that a late or incomplete claim will not be rescued after the event.

Charterer's perspective

The charterer values the time bar as a tool for certainty and for capping the period during which it can be surprised by a demurrage claim. It tends to seek a defined deadline and a clear list of documents, so that the owner must put its claim together promptly and completely or lose it, allowing the charterer to close its books with confidence once the period has run.

The charterer also aligns the bar in its head charter with any bar in its sub-charter or sale contract, so that it has time to pass a claim down the line before its own deadline to claim onward expires. A mismatch can leave the charterer liable upstream while time-barred from recovering downstream, which is a familiar and entirely avoidable trap.

Negotiation points

• The length of the period within which the claim and documents must be presented.
• The precise list of supporting documents required for a compliant claim.
• The event that starts the clock (completion of discharge, final statement of facts, or another point).
• Alignment of the bar with any corresponding deadlines in sub-charter or sale contracts.

Common variations

• A fixed number of days from completion of discharge to present a fully documented claim.
• A bar requiring specified documents, with the claim void if any one of them is omitted.
• A two-tier structure with a shorter period for the claim and a longer one for back-up papers.
• A general claims time bar covering all charter claims rather than demurrage alone.
