Legal Documents Every Startup Needs (Complete Checklist)

A founder in Lagos spent eight months building a product before a bigger company with a near identical name forced a rebrand. The product was fine. The team was fine. The problem was a trademark search that never happened and a filing that got pushed to “next quarter” until next quarter became too late.

This happens constantly, and not because founders are careless. It happens because nobody hands you a list. You find out what documents you needed on the day you needed them and didn’t have them.

So here is the list. It follows the order most businesses actually move through: get registered, sort out who owns what, protect what you’ve built, put your relationships in writing, stay compliant, then raise money. Each stage depends on the one before it, so work through them in order rather than jumping to whichever one feels most urgent today.

1. Documents to register your business

Nothing else on this list matters until your business legally exists, and that’s the first thing a bank, an investor, or a court will ask to see.

Every founder needs:

Certificate of incorporation or registration
Memorandum and Articles of Association (or your jurisdiction’s equivalent)
Tax identification number
Business permit or license, if your sector requires one

The exact paperwork depends on where you’re registering:

In Nigeria, this means CAC filings, name approval, and a specific set of forms.
In Kenya, it means name reservation through the Business Registration Service and its own filing sequence.
In the US, especially as a non resident founder, it means an EIN application, a registered agent, and state specific filings.

Once you’re registered, the next question is usually the one founders put off the longest: who owns what.

2. Documents that define ownership and equity

This is the paperwork that prevents the fight that actually ends companies. Not the product fight. The “who owns what” fight.

You need:

A founders’ agreement covering equity split, vesting, and what happens if someone leaves
A cap table, kept current from day one, not reconstructed from memory before a raise
Share certificates or equivalent proof of ownership for each shareholder
A shareholders’ agreement once you bring in outside investors or a second class of shareholder

A founders’ agreement written after a disagreement starts isn’t a founders’ agreement. It’s a negotiation under pressure. Get it signed while the business is still worth nothing, because that’s when everyone can agree calmly.

With ownership settled, the next thing worth protecting is the brand and product itself.

3. Documents that protect your IP and brand

Your name, your logo, and your product are assets. Without paperwork, they’re assets anyone can take, as the Lagos founder above found out.

You need:

Trademark registration for your name and logo, filed in every market you operate in or plan to enter
An IP assignment agreement, so anything built by contractors or early employees legally belongs to the company, not to them
Copyright registration for original content, software, or creative work, where relevant
Domain and social handle records, kept with your other IP documents

Trademark protection doesn’t cross borders on its own. A registration in Nigeria doesn’t protect you in Kenya, and Kenya doesn’t cover Rwanda. Each market needs its own filing.

Brand and IP secured, the next layer is putting every working relationship in writing.

4. Contracts every startup needs

These are the documents that sit unused in a folder for years, until the day one of them is the only thing standing between you and a lawsuit.

You need:

Employment agreements for every hire, with clear IP assignment and confidentiality terms
Contractor agreements for freelancers and agencies, with scope, payment, and IP ownership spelled out
Non disclosure agreements for anyone seeing sensitive information before a formal deal exists
Vendor and supplier contracts, especially anything involving recurring payment or exclusivity
Terms of service and a privacy policy, if you run a website, app, or anything that collects user data

With contracts in place, the last piece before you’re truly operational is staying compliant on an ongoing basis.

5. Compliance and financial documents

Though they are not exciting, they are also non negotiable.

You need:

Business bank account documentation
Tax filings and statutory returns, on whatever schedule your jurisdiction sets
Payroll and statutory deduction records, once you have employees
Annual returns or equivalent yearly filings to keep your registration active

Missing one annual filing rarely costs you your registration. Missing two years running usually does, and by then backdating isn’t an option.

Get this right and you’re ready for the stage where the paperwork moves fastest: fundraising.

6. Documents you need to raise money

Once you’re raising, investors will not wait for you to catch up on paperwork.

You need:

A pitch deck and financial model. Not legal documents, but investors expect them alongside everything else
A term sheet outlining the proposed investment terms
A SAFE, convertible note, or equity agreement, depending on how the round is structured
An updated cap table reflecting the new investment
A due diligence folder containing every document above, organized and ready to hand over

A messy document trail reads as a messy company, and that’s usually enough to lose a term sheet before anyone questions the actual business.

Where to start

If you haven’t registered yet, start with section 1. If you have a co-founder and no founders’ agreement, stop and fix that before anything else, regardless of what stage you’re at. If you have a name or product you haven’t trademarked, that’s your next move no matter how far along you are.

Building in Nigeria and expanding to the US? Start with the US incorporation document checklist and free guide.

Building a brand across multiple African markets? Start with the cross-border trademark filing checklist.

Frequently asked questions

What’s the first document a new founder needs? Your certificate of incorporation. Everything else, bank accounts, contracts, trademarks, depends on your business legally existing first.

Do I need a lawyer to draft a founders’ agreement? You can start from a template, but any agreement involving equity, vesting, or exit terms should be reviewed by someone who knows your jurisdiction’s company law before signatures go on it.

Does one trademark registration cover multiple African countries? No. Trademark protection is national. A registration in one country doesn’t extend to another, even within the same regional bloc, unless you file separately in each market.

What happens if I skip the founders’ agreement? Nothing, until there’s a disagreement about equity, roles, or an exit. At that point, the disagreement usually gets resolved by whoever has the most leverage, not by what’s fair.
