May said in a BBC interview Wednesday that "there isn't a formal demand. The negotiations haven't started yet."
She did not indicate how much Britain would be willing to pay, saying only that Britain will no longer pay "significant sums of money on an annual basis" to the EU.
But May added: "We're a law-abiding nation. We will meet obligations that we have."

The European Parliament's top official for Brexit negotiations wants a deal on the future rights of the 3 million EU citizens living in Britain and the 1 million Britons living elsewhere in the bloc before the end of the year.
Parliament Brexit co-ordinator Guy Verhofstadt said in an interview with The Associated Press that having that part of the talks ironed out quickly would help provide certainty for EU citizens.
He says the residency agreement could be sealed off as a done deal before it would need to be rubber stamped as part of the overall withdrawal deal after two years.
Verhofstadt said: "It should be a good thing, if we were capable, (to) have an agreement on this before the end of the year so that we can already give that certainty to the citizens even when formally it will be a chapter that will be in the withdrawal agreement."
6:55 p.m.
France's far-right National Front says the EU should work "in a spirit of healthy co-operation" in negotiating Britain's departure from the bloc, and not make the divorce as painful as possible to dissuade other nations from leaving.
French party leader Marine Le Pen, a leading presidential candidate in the election that starts next month, wants her country to leave the European Union and give up the euro currency.
Her party's delegation at the European Parliament said Britain's letter presented Wednesday triggering exit talks is the start of a "renaissance of national ambition until now trampled on" by European Union leaders.

Ayrault said in a statement that Britain's decision "shall be respected" but that it would be up to the 27 remaining EU members "to implement their common will to strengthen the European Union."
Ayrault cited a vow EU leaders took over the weekend to stick together despite differences as they marked the 60th anniversary of the founding treaty that prefigured the EU.

Dastis told lawmakers Madrid will look for a "citizens first" approach to a post-Brexit agreement that is based on the "key principle of reciprocity."
He says the rest of the EU shouldn't concede to British requests to maintain favourable financial treatment "without equivalence in the freedom of people's movement."
Dastis said: "There is no room for any a la carte agreement."

Gibraltar's chief minister says he will fight any attempt by Spain to gain more control over the tiny British territory during negotiations over the United Kingdom's exit from the European Union.
Fabian Picardo told Gibraltar's Parliament on Wedneday: "Our sovereignty is not in play."
Picardo said: "We will be no pawn in Brexit and no victim of Brexit."
Britain has controlled Gibraltar for three centuries and refused neighbouring Spain's demands for joint sovereignty, creating occasional diplomatic tensions.
Gibraltar has a population of around 32,000 and about 96 per cent of the residents who voted in the Brexit referendum voted to remain in the EU.
Picardo says he is hopeful that the trade deals Britain hopes to negotiate with other countries around the world, including the United States and Commonwealth countries, also will benefit Gibraltar.

Tajani added: "Unilateral decisions affecting the rights of EU citizens any time before the U.K.'s withdrawal ... would be contrary to the treaties and therefore illegal."
He says the EU and Britain must finalize the terms of their divorce agreement, including how much money London owes, before discussing trade or other issues.
Tajani said this is "the precondition for any potential future European Union-U.K. partnership. This is not negotiable."

Lithuania's defence minister says Brexit is "very bad for European Union," but predicts it won't affect Europe's security.

Karoblis says: "If speaking of classic security aspects -- NATO's collective system of defence -- there we have full assurances that the U.K. will remain in Europe. And this has been said very clearly."
Lithuania, which was part of the Soviet Union, joined both NATO and the EU in 2004.

Noting that Britain is an important export market for the Czech Republic's economy, he said he wants to make sure future trade relations between the EU and Britain don't change that.
