The Vocabulary of International Private Households: Navigating a Discreet World
Insights | 31.03.2026
NDA? Principal? UHNW? Between city penthouses, sprawling country estates, and private jets, a specialized jargon has emerged that often leaves outsiders baffled. For those looking to succeed in this unique professional environment, mastering these 14 essential terms is non-negotiable.
Anyone catching their first glimpse behind the scenes of an international private household quickly realizes that this isn’t just a place of residence – it is a managed operation. Here, ultra-personal living spaces meet highly professional working environments. This duality is reflected in the terminology: international households speak their own language. Terms such as “rotation,” “live-in,” or “SOP” are far more than mere industry buzzwords. They are the hallmarks of a professional framework that mirrors the structures of global corporations. Mastering this vocabulary offers a vital window into the mechanics of one of the world’s most exclusive professional spheres.
Bespoke
From a butler’s employment contract and the fit of a shirt to a child’s long-term educational roadmap, “bespoke” stands for tailor-made solutions. These are precisely aligned with a household’s specific lifestyle, security requirements, and core values. Those who lead publicly traded companies, achieve peak athletic performance, or shape global politics find sanctuary in a private life that is as individual as it is perfectly taylored.
Chain of Command
The Chain of Command is the formal hierarchy through which decisions and information flow. A clearly defined chain prevents duplication of effort, misunderstandings, and loyalty conflicts – factors that are particularly critical in complex setups involving multiple residences and external service providers.
Contractors
Contractors are external service providers engaged on a project basis to supplement the permanent domestic staff. Their roles may include renovations, specialized deliveries, art transport, or estate landscaping and tree surgery.
Domestic Staff
Domestic staff refers to the personnel employed directly in or for a private household. This spectrum ranges from housekeepers and nannies to private chefs, butlers, chauffeurs, and close protection officers.
Estate
The meaning of “estate” varies by context. In a narrow sense, it describes a property including all associated buildings and land. In a broader, wealth-oriented context, the term is synonymous with a person’s or family’s total assets. This includes global real estate holdings, investments, art collections, vehicles, yachts, and private jets. In the event of a death, “estate” refers to the inheritance to be transferred.
High Profile
Individuals are considered “high profile” if they are well-known to the general public – whether through entrepreneurship, politics, sports, or show business. In these households, security awareness, absolute discretion, and media literacy are essential for all employees, as any lapse in judgment can quickly lead to adverse reputational or security-related consequences.
Know Your Customer / Know Your Client (KYC)
KYC is indispensable when working alongside international decision-makers. For OPMG, this means the recruitment process requires more than just a CV. Relevant certificates, personal references, and a clean police record are mandatory. After all, nannies, private chefs, and drivers work in close proximity to the families of influential figures and are often surrounded by high-value assets. Placements are only made in households that offer appropriate working conditions, and OPMG can conduct on-site assessments upon request before candidates are introduced.
Live-in / Live-out
“Live-in” positions involve employees living directly in the employer’s home or in an annex on the same property. This eliminates the commute, allowing for rapid availability, high flexibility, and seamless care. However, live-in roles require clear agreements regarding working hours and privacy. For “live-out” positions, staff commute from their own private residence to the workplace. In these cases, precise rosters and reliable cover arrangements ensure smooth operations.
Non-Disclosure Agreement (NDA)
The NDA is a confidentiality agreement that mandates absolute discretion – extending even to one’s own spouse and children. These agreements usually remain in effect long after the employment has ended. In international households, NDAs are the gold standard. Neither security-sensitive information nor private gossip must ever leave the premises.
Principals
In the context of international households, “Principals” is the term used to describe the employers or the heads of the household.
Rotation
Rotation refers to cyclical work models. Staff may alternate on a schedule, such as a two-week or three-month rhythm. This ensures 24/7 coverage by nannies, chefs, or security personnel while simultaneously allowing for their necessary rest and recovery.
Standard Operating Procedures (SOPs)
SOPs are written, standardized protocols for recurring processes. These range from daily housekeeping routines and arrival protocols for the Principals to crisis management and evacuation plans. Professional SOPs provide clarity and quality assurance, while also facilitating onboarding and the coordination of rotation-based models.
Travelling Position
Employees in a travelling position regularly accompany their principals on trips. This requires high flexibility, a genuine passion for travel, strong cross-cultural competency, and the ability to maintain routines and security standards across changing environments.
Ultra High Net Worth (UHNW)
UHNW describes families or individuals with assets exceeding 30 million US dollars. In practice, this wealth is typically accompanied by multiple residences, international lifestyles, extensive staff teams, and complex asset structures.
