The rules that run Poland

A law here is a written act passed by parliament and published officially, binding on everyone equally. If it is not written down and published, it is not law, which means you can always check the exact rule.

Poland is a civil-law country, the same family as Germany and France, not common law like the UK or US. In practice the answer to a legal question lives in a written code, not in what a judge ruled in some past case.

Three different things, ranked. A statute (ustawa) is the actual law, a regulation (rozporządzenie) only fills in its detail and can never go beyond it, and internal policy binds nobody. How to tell which one is being used on you.

Two places hold the real text: the codes (kodeksy) that group each area of law, and the official journal that makes it binding. Plus how to read a reference like "Art. 200 KK" when you hit one.

Poland stacks in three tiers below the national government: the województwo (region), the powiat (county), and the gmina (your local commune). National law sits above all of them and always wins, so the same question can have a different local answer one gmina over.

Above even Polish national law sits EU law, which applies here directly and overrides Polish law where the two clash. It governs more of daily life than you would expect, and for EU citizens it is what lets you live and work here without a visa.

Two separate tiers with two separate codes. A wykroczenie is a minor offence and usually just a fine; a przestępstwo is a crime that can mean a record or prison. Which one you are facing changes everything.

A notariusz in Poland is a state-appointed lawyer, not a stamp at the post office, and some things are simply invalid without one. Buying property, forming a company, and granting a power of attorney all have to go through their office.

At 18 you reach pełnoletność, full legal adulthood in Poland.

You must be 18 to buy or drink alcohol in Poland.

You must be 18 to buy cigarettes, tobacco, or vapes in Poland.

You can drive a car (cat. B) from 17 accompanied; lighter vehicles start earlier.

Polish citizens can vote from the age of 18.

The age of consent in Poland is 15, but the law still protects 15 to 17 year olds.
