Social Security

social-security legal skills for CROSS-JURISDICTION

Cross-border social security work turns on the coordination rules that sit between national systems — bilateral totalization agreements, EU Regulation 883/2004 for intra-European postings, and the applicable-legislation certificates that determine where contributions are actually due when a worker crosses a border. Getting that analysis wrong means double contributions, uncredited pension periods, or gaps in sickness and unemployment cover that neither jurisdiction will fill. The agent-ready legal skills assembled under this cross-jurisdiction social security collection in the ThomasMore catalog address exactly those fault lines: mapping which country's scheme applies, checking treaty coverage, and flagging the documentation a posting employer must hold.

Each skill runs over MCP or downloads as a reusable file, so it slots into the workflow of mobility counsel, employment lawyers, and in-house teams managing international assignees without rebuilding logic from scratch for every engagement. Because social security law differs sharply by country pair — a US-UK totalization agreement operates very differently from an intra-EU posting chain — the skills are organised so you can filter by jurisdiction to isolate the regime that governs your matter. Authors maintain these capabilities as bilateral agreements are renegotiated and domestic contribution rules are amended. Use the jurisdiction filters above to narrow the ThomasMore catalog to the specific country pairing your cross-border social security matter requires.
