The biggest worry when changing form is the hundreds of running contracts: can customers, suppliers and banks treat this as a different company and demand re-signing, or even terminate? This article answers with the succession principle of Law 59/2020/QH14 and separates what is a partner’s real right from what is mere notification procedure.
The succession principle: contracts continue with the same legal person
A form conversion creates no substitute new legal person: the converted company inherits all assets, rights and obligations of the pre-conversion company under the reorganisation frame of Law 59/2020/QH14 (the form-conversion articles, Articles 202-205). The enterprise code and tax code do not change, the contract party does not change — only that party’s organisational form changes. Consequently every running contract continues in force without re-signing and without partner consent, and the partner has no right to terminate unilaterally merely because the company changed form, unless the contract itself contains a clause treating a party’s structural or form change as a termination event or requiring prior notice and consent — a clause common in credit agreements, exclusive distribution contracts and contracts with state counterparties.
Contract addenda, partner notice and the seal
Correct practice has three tasks: send a form-change notice with the new enterprise registration certificate to key partners so they update invoice and payment information; sign addenda updating legal information for large long-term contracts or contracts where the partner’s system requires an exact entity-file match (banks, insurers, the state); and handle the seal: under Article 43 of Law 59/2020/QH14 the enterprise itself decides the seal’s type, quantity, form and content — a form change usually changes the abbreviated name and seal information, so the enterprise makes a new seal and notifies the specimen to partners and banks; the old seal is no longer used for transactions after the conversion’s effective date. Skipping these tasks does not void contracts, but creates real friction: rejected invoices and payments held because account and entity information no longer match the partner’s records.
Frequently asked questions
If the company changes its business type, do contracts signed beforehand remain valid?
Fully effective. A form conversion preserves the legal identity: the converted company inherits all rights and obligations under the reorganisation frame of Law 59/2020/QH14, the enterprise code is unchanged, so contracts need neither re-signing nor partner consent. The enterprise only needs to notify partners of the information change for invoice, payment and file updates. The sole exception is a contract with its own clause treating a structural or form change as an event requiring notice, consent or as a termination ground — handle that under its clause.
Do we need to sign a contract addendum to update the company’s new business type?
Not required for validity — the contract runs on without an addendum because the party has not changed. An addendum is for file governance only: long-term, large-value contracts, or contracts with banks, insurers and state bodies whose systems require exact entity information on documents. The addendum records that the company has converted its form, inherits all rights and obligations, and the contract’s other terms remain — it is a confirmation document, not a new contract.
Does a partner have the right to terminate a contract when the company changes its business type?
No, not for the form change alone. A partner’s termination right arises only if the contract has a change-of-control or change-of-form clause allowing termination or requiring prior consent, or if the conversion simultaneously breaches another commitment in the contract (for example a financial-covenant commitment in a credit agreement). The enterprise should review the contracts carrying such clauses before converting and obtain written non-objection confirmations from those partners.
Does the company seal have to be remade when the business type changes?
Usually yes, a new seal is needed because the information on the seal (company name with its form) changes with the new form. Under Article 43 of Law 59/2020/QH14 the enterprise decides its own seal and no longer registers the seal specimen with a state authority as before; the enterprise makes the new seal, issues its use rules, notifies the specimen to banks and key partners, and stops using the old seal from the conversion’s effective date. Documents stamped with the old seal before that date keep their validity.
The message to partners when notifying a conversion should be short and rest on one legal sentence: same legal person, full succession, unchanged enterprise code. Nearly all partner anxiety about contracts dissolves when that sentence is sent with the new enterprise registration certificate — and the few contracts with change-of-control clauses should already be on the earlier review list.
