Form a Delaware Limited Liability Partnership (LLP)

A limited liability partnership is a general partnership that has taken one extra legal step: it has registered with the state to switch on a liability shield for its partners. Take that step away and you have an ordinary general partnership, where each partner can be held personally responsible for the debts, contracts, and negligence of the business and of every other partner. The LLP registration is what converts that exposure into protection.

Delaware governs partnerships under the Delaware Revised Uniform Partnership Act, found in Title 6, Chapter 15 of the Delaware Code. The Act treats the partnership itself as an entity distinct from the individual partners. When a partnership files a Statement of Qualification and becomes a registered LLP, the partners are generally not personally liable for the obligations of the partnership merely because they are partners. That single change is the entire reason the form exists.

The distinction from a general partnership

In a general partnership, liability is joint and several. A creditor with a claim against the partnership can pursue any partner's personal assets, and one partner's malpractice can reach the savings of a partner who had nothing to do with it. The LLP shield removes that vicarious personal liability. Partners are still on the hook for their own wrongful acts and for debts they personally guarantee, but they are no longer automatically liable for the partnership's obligations or for what their co-partners do.

Why professionals gravitate to the LLP

The LLP was designed with licensed professional firms in mind, and that is still where it is most common. Law firms, accounting practices, medical and dental groups, architecture and engineering firms, and consultancies frequently organize as LLPs because the structure preserves the partnership model the professionals already understand while capping each partner's exposure to the partnership's liabilities. If you and your co-owners already think of yourselves as partners rather than as members or shareholders, the LLP keeps that language and that structure intact.

Delaware LLP registration runs through the Delaware Department of State, Division of Corporations. The controlling filing is the Statement of Qualification — the document by which an existing or newly formed general partnership elects to become a limited liability partnership. Delaware publishes its alternative-entity instructions and forms through the Division of Corporations, and the annual tax instructions for partnerships live on the alternative-entity tax page.

The Statement of Qualification records the partnership's name, its principal office, the name and Delaware street address of its registered agent, and the number of partners. Because an LLP grows out of a partnership rather than being created from nothing, the partnership relationship itself is established by the partners' agreement; the state filing is the layer that adds the liability shield and the public record.

What you provide at registration

• Partnership name ending in "Limited Liability Partnership," "L.L.P.," or "LLP"
• Principal office address for the partnership
• Registered agent with a physical Delaware street address
• The number of partners at the time of filing, which drives the annual tax

Processing

Standard processing at the Division of Corporations generally runs on the order of ten business days, with faster expedited tiers available for an added state charge. Once the Statement of Qualification is on record, your LLP exists as a matter of Delaware law and appears in the state's entity records.

Becoming an LLP is not only a paperwork event; it changes the legal footing your business operates on and adds a small set of ongoing duties.

The shield is conditional on staying registered

The liability protection lasts only while the LLP registration is valid. If the partnership lets its Delaware status lapse — by failing to pay the annual tax, losing its registered agent, or otherwise falling out of good standing — the shield can fall away, and partners can find themselves back in ordinary general-partnership territory. Maintaining the registration is therefore not busywork; it is what keeps the protection alive.

The annual obligation

Delaware charges its registered LLPs an annual tax rather than a conventional annual report. The obligation is due June 1 each year and is administered by the Division of Corporations through its alternative-entity tax system. The amount is tied to the number of partners, which is why the state asks for that figure at registration and expects it to be kept current.

Registered agent upkeep

Your Delaware registered agent must remain in place and reachable at a Delaware street address for as long as the LLP exists. If the agent resigns, moves, or is changed, the state's record has to be updated. An LLP without a valid registered agent is out of compliance regardless of whether the annual tax is paid.

The partnership agreement keeps running the business

Delaware does not run your partnership for you. The internal rules — who owns what, how profits are split, how partners are admitted or bought out, how decisions get made — live in the partnership agreement, not in the state filing. The LLP registration adds the shield; the partnership agreement supplies the operating rules.

Every Delaware LLP must name and maintain a registered agent. The agent is the official channel through which the state and the courts reach the partnership. It is where service of process lands if the LLP is sued, and where the Division of Corporations sends compliance notices and annual-tax correspondence.

What the agent handles

• Service of process — lawsuits, subpoenas, summonses directed at the partnership
• Official notices from the Division of Corporations, including annual-tax reminders
• Other formal state correspondence

A Delaware registered agent must have a physical street address in the state; a post office box does not satisfy the requirement. The agent has to be available during ordinary business hours so that documents can actually be delivered and received.

Your options

A partner who lives in Delaware and keeps regular business hours can serve as the LLP's agent, though doing so puts a personal address into the public record. Many out-of-state and privacy-conscious firms instead use a commercial registered agent, which supplies a professional Delaware address, guarantees someone is present to receive documents, and forwards anything that arrives. For partnerships with no physical presence in Delaware — a common situation, since firms often register in Delaware for its legal framework rather than because they operate there — a commercial agent is effectively required.

Mainstay Filing prepares and submits the Delaware LLP registration so you are not navigating the Division of Corporations' forms and alternative-entity tax system on your own. You give us the details the state needs — the partnership's name, its principal office, the number of partners, and your registered agent choice — and we prepare the Statement of Qualification and file it with Delaware.

We include registered agent service, so your firm has a compliant Delaware address on record without a partner's personal address ending up in a public database, and so there is always someone positioned to receive legal process and state mail. After registration, we track the June 1 annual-tax obligation and can handle that filing for you, which keeps the liability shield from lapsing over a missed deadline.

Where our role ends

We are a filing service, not a law firm or an accounting firm. We do not draft your partnership agreement, advise on how to divide profits or admit partners, or provide tax opinions. Those decisions belong with your own attorney and CPA — and for a professional LLP, they often belong with your licensing board as well. What we do is make the state-facing registration accurate and timely so the entity is real, protected, and in good standing.
